Question

Your friend spends 3+4x minutes lifting weights and 9x+5 running a treadmill. Write a polynomial that represents how much time is spent on running on the treadmill than lifting weights. Answer quick!!!

Answer 1

`Polynomial = 5x+ 2`

Explanation:

Given

`Weights = 3 + 4x`

`Treadmill = 9x + 5`

Required

Polynomial that represents time spent running treadmill than weight lifting

To do this, we simply subtract weights from treadmill

i.e.

`Polynomial = Treadmill - Weights`

`Polynomial = 9x + 5 - (3 + 4x)`

`Polynomial = 9x + 5 - 3 - 4x`

`Polynomial = 9x - 4x+ 5 - 3`

`Polynomial = 5x+ 2`
