Answer:the length of the rectangle is 28
The width of the rectangle is 16
Step-by-step explanation:
The given equations are set up to determine the dimensions of a rectangle. L represents the length of the rectangle. W represents the width of the rectangle. Let us label
2L + 2W = 88 as equation 1.
We would substitute L = W + 12 into equation 1, it becomes
2(W + 12) + 2W = 88
2W + 24 + 2W = 88
4W + 24 = 88
4W = 88 - 24 = 64
W = 64/4 = 16
Substituting W = 16 into L = W + 12, it becomes
L = 16 + 12 = 28
54 - 4a^2 + 3b^3 when a = -2 and b = 4 is
54 - 4(-2)^2 + 3(4)^3 = 54 - 4(4) + 3(64) = 54 - 16 + 192 = 230
