Answer:
4 inches
Step-by-step explanation:
The equation for volume of a rectangular prism is V=lwh, where l=length, w=width, h=height.
We are given the volume, length, and width, so let's put those in and solve for the height.
V = lwh
660.24 = 13.1*12.6*h
660.24=165.06h
660.24/165.06 = h
4 = h
<u>The height is 4 inches.</u>
Answer:
pretty sure the tree's 20 feet
Answer: B
<u>Step-by-step explanation:</u>
x³ - 3x² + 16x - 48 = 0
→ x²(x - 3) + 16(x - 3) = 0
→ (x² + 16) (x - 3) = 0
→ (x² - (-16)) (x - 3) = 0
→ (x - 4i)(x + 4i)(x - 3) = 0
→ x - 4i = 0 x + 4i = 0 x - 3 = 0
→ x = 4i x = -4i x = 3
