(10^2 +10^2)^.5 = 10*(sqrt2)
Answer:
C
Step-by-step explanation:
4(8-x)=8
32-4x=8
-4x=-24
x=6
Answer:
Step-by-step explanation:
A rectangle is shown with length x plus 10 and width 2 x plus 5.
so the rectangle area = length * width
= (x + 10) * (2x + 5)
an unshaded square with length x plus 1 and width x plus 1
so the unshaded square area = (x + 1) * (x + 1)
the shaded area = rectangle area - square area
= (x + 10) * (2x + 5) - (x + 1) * (x + 1)
= (2x^2 + 20x + 5x + 50) - (x^2 + x + x + 1)
= x^2 + 23x + 49
V = L * W * H
V = 4 * 4 * 8
V = 16 * 8
V = 128 cubic ft
