Question:

Miriam is making a bulletin board that is shaped like a square. She has 72 inches of border material. If x represents the length of one side of the bulletin board, which inequality model and solution set best represents the possible side lengths of Miriam's bulletin board?​

Answer:

x \le 18

Step-by-step explanation:

Given

Border\ Material = 72

Required

Determine an inequality for x

Represent the side lengths of the border with y. So:

Since the border is on the 4 sides, then

4y = 72 -- i.e. the perimeter of the border material

Solve for y

y =\frac{72}{4}

y =18

Recall that x represents the board's side length.

Since x will be situated inside the boarder, then.

x \le y

Substitute y =18

x \le 18

How to factor z^12 - 64 (question 17.)
aivan3 [116]
(z^6 - 8)(z^6 + 8) is the answer. If you verify this by multiplying, you will see that: (z^6 - 8)(z^6 + 8) = z^(6+6) + 8z^6 - 8z^6 - 64 = z^12 + 0 - 64 = z^12 - 64 Hope this helps, Brian
