Find Perimeter Writing Algebraic Expressions

The perimeter of a square with length x is given as

• 2x

• 4x

• x²

• x³

Write the expression for the perimeter of the rectangle

• 6x - 6

• 4x + 10

• 8x - 8

• 3x - 3

The lengths of two adjacent sides of rectangle are 2x + 3 and x -7, and its perimeter is 40. Which answer choice shows an equation that can be used to find the perimeter of the rectangle?

• 2x + 3 = x - 7

• (2x + 3) + (x - 7) = 40

• 2(x + 3 - 7) = 40

• 2(2x +3) + 2(x - 7) = 40
