Answer:
It would be 12.
Step-by-step explanation:
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>
Answer:
b. 4x^2 -7x +5
Step-by-step explanation:
When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...
(7x^2 -5x +4) - (3x^2 +2x -1)
= (7 -3)x^2 +(-5 -2)x +(4 -(-1))
= 4x^2 -7x +5 . . . . . matches B
Answer:
C. y=1/2x-6
Step-by-step explanation:
The correct answer is C. y=1/2x-6.
If we are finding 1/2 of the length, and the length is represented by x, than we would have 1/2x.
It also says 6 less than halve of the length, so we would represent that as 1/2x-6, and that shows us the proper equation to find the width.
Hope this helps!
