Answer:
−2w−14
You have to collect like terms and simplify
<span> x2 – 12x + 36 = 4
(x - 6)^2 = 2^2
x - 6 = 2
x = 8
-(x - 6) = 2
-x + 6 = 2
-x = -4
x = 4
answer
</span><span>C. {4, 8}</span>
Answer:
C. It means to input a -2 into the function to find the output.
Step-by-step explanation:
f(x) means to the function of x. The question is asking you to input -2 for x and find the answer.
We are given area of the ribbon = 144 square inches.
We know formula for side of a square =
.
Plugging value of area in the formula, we get
Side of the square 
= 12 inches.
Sonya wants to sew ribbon along each side of a square pillow.
So, we need to find the perimeter of the square pillow.
<h3>Perimeter = 4 × side = 4 × 12 = 48 inches.</h3><h3>Therefore, she buy 48 inches of ribbon to have the exact amount that she needs.</h3>
