12. Multiply the following binomials:

a. (x + 3)(x - 4)

b. (s - 2)(2s - 12)

c. (4s - 12)(2s + 4)

d. (2x - 4)(2x - 4)

**Answer:**

**a) x^2 - x -12**

**b) 2s^2 - 16s + 24**

**c) 8s^2 - 8s -48**

**d) 4x^2 - 16x + 16**

**Answer:**

a. x^2 - x - 12

b. 2s^2 - 16s + 24

c. 8s^2 - 8 - 48

d. 4x^2 - 16 + 16

**Step-by-step explanation:**

You need to use distributive property find the answer.

(x + 3)(x - 4)

>> (x)(x) = x^2

>>(x)(-4) = -4x

(3)(x) = 3x

(3)(-4) = -12

The result will be x^2 -4x + 3x -12

You can simplify this by adding the like terms:

x^2 -4x + 3x -12

>> x^2 - x - 12

Just do the same for the rest of them by using distributive property.

Hope this helps! Have a great day! Also, let me know if you need an explanation for the rest of them too!

Find the value of x in the isosceles triangle shown below

**Answer:**

x = 10

**Step-by-step explanation:**

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

[tex]\sqrt{74} ^{2}[/tex] = [tex]7^{2}[/tex] + [tex](\frac{x}{2}) ^{2}[/tex]

74 = 49 + [tex]\frac{x^{2}}{4}[/tex]

74 - 49 = [tex]\frac{x^{2}}{4}[/tex]

25 = [tex]\frac{x^{2}}{4}[/tex]

therefore, x = [tex]\sqrt{25*4}[/tex] = [tex]\sqrt{100}[/tex] = 10

X=10 you’ll have to break down your equation to solve the square root.

A right triangle has sides of length 3, 4, and x. Find x if it is one of the legs.

When astronauts Neil Armstrong and Buzz Aldrin first walked on

the moon in 1969, they were able to bounce from step to step!

This is because the gravitational force of the moon is about

16.5% of that of the Earth. If you visited the moon,

weighing 100 pounds on Earth, what would your weight be?

**Answer:**

16.5 pounds

**Step-by-step explanation:**

16.5% as a decimal is 0.165

0.165 x 100 = 16.5

So in conclusion you will weigh about 16.5 pounds on the moon.

About 16 if we are counting the fact that the moons gravity is about 16.5 of the earth you will weight 16.5 pounds and will be able to float!

Grant mows lawns for extra money. He mows 9 lawns in 9 hours on Wednesday and 6 lawns In 6 hours on Saturday.

What is the constant of proportionality that relates the total number of lawns mowed, y, to the number of hours mowing lawns, x?

**Answer:**

the constant is 1. 9/9 is the same as 1. so 9hours over 9 lawns is 1.

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.

Cara's Flower Arrangements

White 3 6 9 12 15

Yellow 5 10 15 20 25

Hector's Flower Arrangements

White 4 8 12 16 20

Yellow 6 10 14 18 22

Part A

Are the numbers of white and yellow flowers in Cara's arrangements proportional?

Which equation relates the number of white flowers, w, to the number of yellow flowers, y?

A. Yes; y=35w

B. Yes; y=53w

C. No; y=3w+5w

D. No; y=5+3w

Part B

Are the numbers of white and yellow flowers in Hector's arrangements proportional?

Write an equation to relate the number of white flowers, h, to the number of yellow flowers, e.

A. Yes; e=32h

B. Yes; e=23h

C. No; e=h+2

D. No; e=h−2

**Answer:**

**Step-by-step explanation:**

Part A

Yes, there is a proportional relationship in Cara's. For every 5 yellow flowers, there are 3 white flowers. 5:3. I didn't see an equation that would work for the equation in the question. The equation I found on my own would be 5w/3 = y

Part B

There is no proportional relationship in Hector's. The equation would be e=h-2.

Write an equation representing the relationship of 10:20 shown in the graph

Which of the following equations results in no solutions?

A 3(v + 5) = 2v - 4 + v

B 3(v + 5) = 2v + 15 + v

C 3(v + 5) = 2v + 15

D 3(v + 5) = 2v - 4

**Answer:**

Combine like terms:

[tex]\sf 3\left(v+5\right)=3v-4[/tex]

Expand:

Subtract 15 from both sides:

[tex]\sf 3v+15-15=3v-4-15[/tex]

[tex]\sf 3v=3v-19[/tex]

Subtract 3v from both sides:

[tex]\sf 3v-3v=3v-19-3v[/tex]

[tex]\sf 0=-19[/tex]

[tex]\boxed{\sf{No\:Solution}}[/tex]

_________________

Subtract 15 from both sides:

[tex]\sf 3v+15-15=3v+15-15[/tex]

HOW DO YOU FIND RADIUS

**Answer:**

you can divide the diameter by 2 or divide the circumference by 2pi

**Step-by-step explanation:**

If the circumference of a circle is given:

Let the radius be r.Say, that the circumference is given as C.By using the formula,[tex]2\pi \: r = C \\ = > r = \frac{C}{2\pi} [/tex]So, to find radius of a circle when circumference is given, we have to divide the circumference with 2π. Then, we will get the radius of the circle.Note : You have to consider π as 22/7 or 3.14. Or the value will be given in the question.If the diameter of a circle is given:

Let the radius be r.Let the diameter be D.By using the formula,2r = D[tex] = > r = \frac{D}{2} [/tex]Hence, if the diameter of a circle is given, we have to just divide the diameter with 2. Then we will get the radius of the circle.Hope you could get an idea from here.

Graph the solution to this inequality on the number line. −1/3x + 1/2 ≥ −3/4

**Answer:**

4.5 (4.5 units to the left of 0) Make sure to draw a solid dot over 4.5 and an arrow pointing in the right direction.

>= is the greater than or equal to symbol

**Step-by-step explanation**

**1. Combine like terms**- In this problem, the like terms are 1/2 and -3/4, so to move 1/2 over to the other side of the equation, we have to divide each side by 2/1, which is the same as multiplying each side by 2: -1/3x + 1/2 * 2 >= -3/4 * 2.

**2. Separate the fraction from x**- Now, we simply divide each side by -3/1, which is the same as multiplying each side as -3: -1/3x * -3 >= -3/2 * -3

**3. Graph on the number line**- We've found that x = 4.5. To check, substitute in 4.5 for the value of x: -1/3(4.5) + 1/2 >= -3/4. -1 >= -3/4 is a true inequality. To graph it on the number line, draw a solid dot over 4.5 and an arrow in the direction of the righthand side.

Jaylen's beta fish tank holds 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. What is the flow rate of the water in gallons per minute? (label your answer gpm) pls dont delete or post links Ty worth 29 points and brainlyiest

**I had this same question! ill tell you what i got.**

**Answer:
**

**12/5
**

**
Step-by-step explanation:
**

**
**

**His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A (5/12) because he is filling more than 1 gallon per minute. You can divide 4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.**

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.

what is the fraction for the right handed people

**Answer:**

**Step-by-step explanation:**

12% is equivalent to 12/100. This reduces to 3/25. Thus, **3/25ths of the students are left-handed**. The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths. **There are more right-handed people (22/25ths) versus left-handed people.**

Yes the answer above is right. 12% of the class is left but in fraction form it is 12/100 because a whole percent is 100% so 12 out of 100 is 12% :) hope it helped

Amelia has 100$ in her savings account and plans on solving 20$ per week. Which equation is right?

1. y= 20x+100

2. y= 100x + 20

3. y=100x

4. y=20x

**Answer: I think it is number 1. y=20x+100**

It is number 1 because the word per signals you need a variable next to the number attached to that per so it is 20x and she already has 100 so it is number 1. 20x+100

Tony usually saves 1/5 of his allowance. Last week, he only saved 2/3 as much. How much of his allowance did he save last week?

**Answer:**

2/15

**Step-by-step explanation:**

All we have to do is multiply 1/5 by 2/3

1 x 2 = 2

5 x 3 = 15

Therefore, Tony saved 2/15 of his allowance last week.

**Answer:**

2/15

**Step-by-step explanation:**

you have to multiply 1/5 by 2/3

1 x 2 = 2

5 x 3 = 15

Therefore, Tony saved 2/15 of his allowance last week.
