A rectangular prism has a volume 144 centimeters. The base is a square with a length of 4 cm. What is the height of the prism?
Vitek1552 [10]
The volume is the product of the height and the area of the base.
  V = Bh
The area of the square base is (4 cm)² = 16 cm², so the height can be found from
  144 cm³ = (16 cm²)h
  h = (144 cm³)/(16 cm² = 9 cm

The height of the prism is 9 cm.

Create an equivalent expression by simplifying the expression below.
BabaBlast [244]

Answer:

see explanation

Step-by-step explanation:

Given

- \frac{1}{2} [ - \frac{3}{2} c + 6c + 1 ] - 3c

Distribute the square bracket by - \frac{1}{2}

= \frac{3}{4} c - 3c - \frac{1}{2} - 3c ← combine like terms

= \frac{3}{4} c - 6c - \frac{1}{2}

= \frac{3}{4} c - \frac{24}{4} c - \frac{1}{2}

= - \frac{21}{4} c - \frac{1}{2}
