What steps do I need to take to solve the last part of this equation and how do I solve them using the quadratic formula?
Answer:
simplify the radical
Step-by-step explanation:
You have shown the solution using the quadratic formula.
The final step is to simplify the radical expression. That is done by factoring out perfect squares and simplifying the fraction.
[tex]x=\dfrac{\pm\sqrt{120}}{12}=\dfrac{\pm\sqrt{2^2\cdot30}}{12}=\dfrac{\pm2\sqrt{30}}{12}\\\\x=\dfrac{\pm\sqrt{30}}{6}=\left\{\dfrac{1}{6}\sqrt{30}\,,\ -\dfrac{1}{6}\sqrt{30}\right\}[/tex]

Additional comment
0 is the additive identity element, so adding or subtracting zero changes nothing.
[tex]0\pm\sqrt{120}=\pm\sqrt{120}[/tex]
Which of the following is NOT a statistical question?
A) How many pets are owned by my uncle?
B) How many pets are adopted in a pet store each week?
C) How many pets are owned by the individual teachers in my school?
D) How many pets are owned by the individual students in a karate class
Answer:
A) How many pets are owned by my uncle.
Step-by-step explanation:
This question is NOT statistical because it has a definite answer.
There is one number that can represent how many pets are owned by let's say your uncle.
On the other hand, B, C, and D compare two different things.
Hope this helps!

Solve this pls 4x+32=5x-22
Answer:
54
Step-by-step explanation:
4x + 32 = 5x -22
Group like terms
32 + 22 = 5x - 4x
54 = X
X = 54
Answer:
x = 54
Step-by-step explanation:
4x + 32 = 5x - 22
5x - 4x = 32 + 22
x = 54
To clarify this,
(4 x 54) + 32 = 248
(5 x 54) - 22 = 248

If the ratio of the rectangular prisms' volumes is 1:8, what is j?
Kalyue drew a rectangle with a perimeter of 20 inches. Then he tried to draw a square with a perimeter of 20 inches. What are the dimensions of square with a perimeter of 20 inches?
Step-by-step explanation:
a square has 4 identical sides.
so, when you have to "walk" around the perimeter of a square you have to go 4 times the same distance.
therefore
20 = 4×side length
side length = 20/4 = 5 in
it is a 5 in × 5 in square.
FYI a rectangle has 2 pairs of sides that are equally long inside their pair.
and so you have in this case a perimeter of
2×6 + 2×4 = 12 + 8 = 20 in
Find the area please!
*you can use decimals if needed*
Answer:
116 km squared
Step-by-step explanation:
When you get crazy shapes like this, try and look for the basic ones inside (i.e. triangles, rectangles, etc.) I can find one big triangle and two rectangles, one small and one larger. Vide the attatchment for reference.
Step 1. Find the missing variables, x, y, and z
y = 2
x = 6 - 2 = 4
z = 8 + (4) + 2 = 14
Step 2. Find the area of each shape
Triangle:
Area = bh/2 = (8 x 14)/2 = 56 km sq
Big rectangle:
Area = bh = 8 x 6 = 48 km sq
Small rectangle:
Area = bh = 2 x 6 = 12 km sq
Step 3. Add all the areas together
56 + 48 + 12 = 116 km sq

To find a fraction between 1/4 and 1/5:
1. Make common denominators with both fractions. The larger the common denominator, the more you will find.
2. Choose any fraction between 1/4 and 1/5. That fraction will be in between 1/4 and 1/5.
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
[tex]\dfrac{1}{4}\ \text{and }\dfrac{1}{5} \ \rightarrow \ \dfrac{1 \times 40}{4 \times 40} \ \text{and} \ \dfrac{1 \times 32}{5 \times 32} \ \rightarrow \ \dfrac{40}{160} \ \text{and} \ \dfrac{32}{160}[/tex]
Now, you may choose any fraction between 40/160 and 32/160.
My chosen fraction is 35/160, which when simplified, gives 7/32.

Answer:
[tex]\dfrac{9}{40}[/tex]
Step-by-step explanation:
Subtract 1/5 from 1/4, divide by 2, then add to 1/5:
[tex]\implies \dfrac{\frac14-\frac15}{2}+\dfrac15[/tex]
[tex]\implies \dfrac{\frac{5}{20}-\frac{4}{20}}{2}+\dfrac15[/tex]
[tex]\implies \dfrac{\frac{1}{20}}{2}+\dfrac15[/tex]
[tex]\implies \dfrac{1}{20} \times \dfrac12+\dfrac15[/tex]
[tex]\implies \dfrac{1}{40}+\dfrac15[/tex]
[tex]\implies \dfrac{1}{40}+\dfrac{8}{40}[/tex]
[tex]\implies \dfrac{9}{40}[/tex]

Solve for h. h - 45 = -35A.h = -10B.h = 10C.h = -80D.h = 80
PLS HELP HURRY
Please Help ! What is the slope of the line?
Answer:
There are 3 ways to find the slope of a line.
I'll use a simple method.
First, let's look at a random point on this line(and make sure it's close to the start of the line).
I'll choose (1,4).
Then, see how much it rises and how far it runs to another fixed point.
Though, in this case we can see that the rise is going down and the run is moving towards the right. So, the slope will be negative since the rise is negative.
You always want to confirm if it'll be a negative or positive slope and which direction the slope is guiding you to.
Now, if we go down 8 and over 3, we'll reach a fixed point of (4, -4).
Therefore, we can infer that the slope of this line will be 8/3.
Answer:
8/3
Step-by-step explanation:
