factor the equation y=9x²-18x+9
Answer:
9(x-1)(x-1) or 9(x-1)²
Step-by-step explanation:
9x² - 18x + 9
factor out a 9
9(x² - 2x + 1)
use middle term factorization to factor x² - 2x + 1
9(x-1)(x-1) or 9(x-1)²
Middle term factorization explained:
For x² - 2x + 1, you want to find 2 numbers that multiply to +1 and add to -2. You then split x² to x and x and add the 2 numbers individually to x.
It should look something like (x+1st number)(x+2nd number)
the two numbers that multiply to get to 1 and add to get to -2 are -1 and -1
( -1 × -1 = 1 and -1 + -1 = 2 )
so we then add the number to the split x² to get (x-1)(x-1) which is the same as (x-1)², the 9 is then added to the factored form to get 9(x-1)(x-1) or 9(x-1)²

NEED HELP ASAP!! WILL MARK BRAINLIEST! John gets a $1000 bonus at work and decides to invest it. He puts his money into an account that earns an annual interest rate of 6.5% compounded once a year. He also decides to add $1200 to his account each year.
How many years will it take for John's account be worth $10,000?
Answer:
I think 4 years
(not sure)
Answer: 7.1 years
Step-by-step explanation:
Lets write a simple interest expression for this:
SI = P(1 + rt)
10,000 = 1,000(1 + 0.065[t])
This model is not quite complete yet, since he is adding 1200 every year. To fix this, we simply add a constant term, 1200t, where t is the number of years that have passed.
10,000 = 1,000(1 + 0.065[t]) + 1200t
Now we just need to evaluate this:
10,000 = 1,000 + 65t + 1200t
9,000 = 1265t
.: t ≅ 7.115
It will take about 7.1 years

P(x) = 4x^3 - 6x^2 + ax – 2. Find a If P(3) = 2.
[tex]P(x)=4x^3-6x^2+ax-2\\\\P(3)=2\\\\\implies 4\cdot 3^3-6 \cdot 3^2 +3a-2=2\\\\\implies 108-54-4 +3a=0\\\\\implies 50+3a=0\\\\\implies a = -\dfrac{50}3[/tex]
Answer:
The value of a = -16.6.... or -16.7
Step-by-step explanation:
Given :
P(3) = 2
P(x) = 4x^3 - 6x^2 + ax – 2
=> 2 = 4(3)³ - 6(3)² + a(3) -2
=> 2 = 4(27) - 6(9) +3a - 2
=> 2+2 = 108 - 54 +3a
=> 4 = 54 + 3a
=> 4-54 = 3a
=> -50 = 3a
=> -50/3 = a
=> a = -16.6.... or -16.7

Step-by-step explanation:
Use a proportion.
8/8160 = 12/x
8x = 8160 × 12
x = 1020 × 12
x = 12,240
Answer: 12,240 W
A glass jug can hold (p + 6) quarts less water than a plastic container, 2 glass jugs and
2 plastic containers contain 6p quarts of water in all
how much water can the plastic container hold? give your answer is terms of p.
Answer:
12
Step-by-step explanation:
collect the like terms and divide
(p+6)2×2=64p+24=6p1) Water in a plastic container, p'= 10 - 3 p
2) Water in a glass container = 27 quarts
Water in a plastic container = 1 quarts
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A glass jug can hold (p + 6) quarts less water than a plastic container, 2 glass jugs and 2 plastic containers contain 6p quarts of water in all.
Now,
Let j represents water in one glass jag while p' represents the water in one plastic container,
Hence, According to the question,
⇒ j - p' = 6p+8 --------(1)
And, 2j+2p'=56p --------(2)
2 × equation (1)
⇒ 2 j - 2 p' = 12p + 16 ---------(3)
Equation (2) + equation (3)
We get, 4 j = 12 p + 72
⇒ j = 3 p + 18
Putting this value in equation (1),
We get, 3p+18-p'=6p+8
p' = -3p + 10 = 10 - 3p
Thus, water in a plastic container, p'= 10 - 3 p
b) If p=3
Water in a glass container = 3 × 3 + 18 = 27 quarts
Water in a plastic container = 10 - 3 × 3 = 1 quarts

What’s the area of the circle?
Answer:
153.86
Step-by-step explanation:
The area of a circle is π[tex]r^2[/tex].
Since the radius of that circle, and we are using 3.14 for π, we get:
[tex]3.14 * 7^2 = 153.86[/tex]
Answer:
Technically you should get :153.94
But for your answer choice its the 2nd one.
Step-by-step explanation:
area=πr^2
Which means that you would plug in 7 for r.
Which means it would look like this: area=π7^2
Next you would square 7 which comes out to 49
Lastly multiply 49 time π (3.14)
Suppose a triangle has two sides of length 42 and 35, and that the angle

OC.
2²=42²+35²-2(42)(35)cos120°
D. c=42+352(42)(35)cos120°
Answer:
The correct option is C because it shows the accurate cosine rule
Equation to get the third side : [tex]c = \sqrt{(42^2 +35^2 -2\times 42\times35\times cos(120\degrees ))}[/tex]
The correct option is C.
Given, that sides of triangle are 42 cm and 35 cm .
The third side can be found using the Law of Cosines,
[tex]c^2 = a^2 +b^2 - 2ab\times cos(C)[/tex]
where C is the angle opposite the third side (c) .
For the given side lengths, then the third side can be found .
Here,
a = 42
b = 35
∠C = 120°
Substitute the values,
[tex]c = \sqrt{(42^2 +35^2 -2\times 42\times35\times cos(120\degrees ))}[/tex]
[tex]c = \sqrt{1764 + 1225 + 1470} \\c = \sqrt{4456}\\c = 66.75[/tex]
Hence the third side is of 66.75 units.
The correct option is C .

Answer:
m∠5 = 75°
Step-by-step explanation:
Angle 2 and Angle 4 are the same as they are alternate interior angles.
Since m∠2 = 45°
We then have m∠4 = 45°
We are given m∠3 = 60°
Now, we just have to find 7∠5.
The sum of the angle of a triangle adds up to 180°.
So, m∠3 + m∠4 + m∠5 = 180°.
60° + 45° + m∠5 = 180°.
Solving for ∠5
m∠5 = 180° - (60° + 45°)
m∠5 = 180° - (105°)
m∠5 = 75°
One side of a rectangle is 7 inches longer than another side. If the longer side of this rectangle decreases by 3 inches, and the shorter side increases by 2 inches, the area of the new rectangle equals the area of the original rectangle. Find the dimensions of the original rectangle.
Answer:
Length = 8+7 = 15
Width = 8
Step-by-step explanation:
New
Length = x+7 , x+4
Width = x ,x+2
(x+7) x = (x+4)( x+2)
expand and simplify x =8
The length of the shorter side length of original rectangle is 8 inches and of original rectangle longer side length is 15 inches.
Area of rectangleLet l is the length and b is the breadth of the rectangle.
then the area of the rectangle is ab.
How to find the dimensions of the original rectangle?Given One side of a rectangle is 7 inches longer than another side.
then shorter side length is x and the large side length is 7+x.
then the area of the original rectangle is x(x+7)
Now calculate the sides of the new rectangle.
longer side of this rectangle decreases by 3 then new side is 7+x -3= 4+x
The shorter side increases by 2 inches then x+2.
So new rectangle area is (x+4)(x+2)
Both rectangle area is equal then
(x+4)(x+2) = x(x+7)
x² +2x+4x+8 = x²+7x
x²+6x+8 = x²+7x
x²-x²+7x-6x = 8
x = 8
Since a shorter side length is 8 inches and a longer side length is 8+7 =15 inches.
