Question

26) What is the perimeter of a rectangle whose
lengths are 9x + 5 and widths are 7x + 2?

Answer 1

32x + 14

Explanation:

The opposite sides of a rectangle are equal, so

perimeter = 2(9x + 5) + 2(7x + 2) ← distribute parenthesis

= 18x + 10 + 14x + 4 ← collect like terms

= 32x + 14

Answer 2

32х+14

Explanation:

`2(9x + 5 + 7x + 2) \\ 18x + 10 + 14x + 4 \\ 32x + 14`
