Question

Malcolm is given a plan for a garden. He expresses the perimeter as 2(x+8) + 2(3x). WHAT WILL BE THE COEFFICIENT OF X WHEN HE SIMPLIFIES THE EXPRESSION?

Answer 1

The coefficient of x is 8

Explanation:

Given

`P = 2(x+8) + 2(3x)` --- Perimeter

Required

Determine the coefficient of x

`P = 2(x+8) + 2(3x)`

Open bracket

`P = 2x + 16 + 6x`

Collect like terms

`P = 2x + 6x+ 16`

`P = 8x+ 16`

The coefficient of x is 8
