Answer:
Width = 12
Length = 16
Step-by-step explanation:
Width = x
Length = x + 4
2x + 2(x+4) = 56
2x + 2x + 8 = 56
4x = 56 - 8
x = 48/4
x = 12
Since the number before the number in the tenth place (7) is greater than 5 (8), you will be rounding up. So your answer is 9.80
Step-by-step explanation:
it says f(-4).
so, x = -4.
into what function segment is this "falling" ?
well, into the x < 3 segment, right ? because -4 < 3.
so, we need to use
f(x) = x² - 5
f(-4) = (-4)² - 5 = 16 - 5 = 11
