(4x + 2) more minutes is spent running on the treadmill than lifting weights
<em><u>Solution:</u></em>
Given that,
your friend spends 6+5x minutes lifting weights
9x+8 minutes running on a treadmill
Therefore,
Time spent on lifting weight = 6 + 5x minutes
Time spent on treadmill = 9x + 8 minutes
<em><u>Write a polynomial that represents how much more time is spent running on the treadmill than lifting weights</u></em>.
Thus we need to find the difference between time spent on treadmill and time spent on lifting weight
Difference = Time spent on treadmill - Time spent on lifting weight
Difference = 9x + 8 - (6 + 5x)
Difference = 9x + 8 - 6 - 5x = 4x + 2
Thus 4x + 2 more minutes is spent running on the treadmill than lifting weights
