Question

The table shows the length and width of a rectangle.

Dimension Measurement

(units)

Length 3x+6

Width 2x−4

Write a simplified expression for the perimeter of the rectangle.

__ units

Answer 1

Perimeter = twice the Length+width

P=2(L+w)= 2(3x+6 +2x-4)

= 2(5x+2)

= 10x +4

P(x) = 10x +4
