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:

Step-by-step explanation:
Given

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
-- i.e. the perimeter of the border material
Solve for y


Recall that x represents the board's side length.
Since x will be situated inside the boarder, then.

Substitute 

Answer: I believe it is C. hope it helps/

Answer:
(4, - 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[
,
]
Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then
midpoint = (
,
) =
,
) = (4, - 0.5 )
