Answer:

[tex]Polynomial = 5x+ 2[/tex]

Step-by-step explanation:

Given

[tex]Weights = 3 + 4x[/tex]

[tex]Treadmill = 9x + 5[/tex]

Required

Polynomial that represents time spent running treadmill than weight lifting

To do this, we simply subtract weights from treadmill

i.e.

[tex]Polynomial = Treadmill - Weights[/tex]

[tex]Polynomial = 9x + 5 - (3 + 4x)[/tex]

[tex]Polynomial = 9x + 5 - 3 - 4x[/tex]

[tex]Polynomial = 9x - 4x+ 5 - 3[/tex]

[tex]Polynomial = 5x+ 2[/tex]
