Answer:
x = 2
Step-by-step explanation:
10 -4 (2x-1) = -2(3-x)
10 - 8x + 4 = -6 + 2x
-10x = -6 -10-4
-10x = -20
x = -20/-10
x = 2
Answer: d. s ≥ 23
Step-by-step explanation:
Let s be the side of the square.
We know that the perimeter of a square =4s
Let f(s)=4s
If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

Divide both sides by 4, we get

Thus, d. is the right answer. The reasonable domain of f(s) is
