I believe it is -7 but I may be misunderstanding the question
Answer:
<em>Hey mate, here's ur answer:</em>
<em>---------------------------------------------------</em>
<em>-2x^5. 4x^2 </em>
<em>=(−2)*x5*4*x2
</em>
<em>=−8*x7
</em>
<u><em>=−8x7</em></u>

We will be using the formulas:
speed=distance/time
time=distance/speed
distance=speed×time
First let's find out Diane's rate of swimming. We can measure this by finding the slope (y/x) of a given coordinate on the graph. One point is (10,15), so you do 15/10=1.5m/s
Now for Rick's rate of swimming, just take a pair of values from the table. 12.5/10=1.25m/s
By the way m/s is metres per second for this
So at a constant speed of 1.5m/s, Diane swam 150m in 150/1.5= 100 seconds, or 1 minute 40 seconds
And at a constant speed of 1.25m/s, Rick swam 150m in 150/1.25= 120 seconds, or 2 minutes.
So the difference between their two times is 20 seconds
