Samir knows that the volume of a prism is 40 cubic units. He also knows that the width of the prism is 2 units and the height is 5 units What is the length of the prism

The answer to your question is 4 units

Step-by-step explanation:

Data

Volume = 40 u³

width = 2 u

height = 5 u

length = ?

Formula

Volume of a prism = width x height x length

Solve for length

        length = Volume / (width x height)

Substitution

        length = 40 / (2 x 5)

Simplification

        length = 40 / 10

Result

        length = 4 u

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
