Answer:

Step-by-step explanation:

Formula used =

The problem 10bf + 25bg – 21p – 14pq cannot be factored because it cannot be simplifed further. This is because there are no common factors between in any of the terms.
Answer:
If one −5s−7(8s−1): -61s+7
If two −5s−7(8s−1): -112s+14
Step-by-step explanation:
-5s-7(8s-1)
Multiply -7 onto 8s and -1:
-5s-56s+7
add -5s and -56s:
-61s+7
−5s−7(8s−1)−5s−7(8s−1)
Multiply both -7 to 8s and -1
-5s-56s+7-5s-56s+7
add:
-112s+14
Answer: 1.35, 2.5, 1.8
Step-by-step explanation:
<u><em>Answer:</em></u>
Evans was the fastest
<u><em>Explanation:</em></u>
<u>The relation between velocity, time and distance is as follows:</u>

<u>1- For Cutwright:</u>
We have the time = 84 minutes and the distance = 35 laps
<u>This means that:</u>
velocity =
= 0.61667 lap/minute
<u>2- For Evans:</u>
We have time = 96.6 minutes and distance = 42 laps
<u>This means that:</u>
velocity =
= 0.43478 lap/minute
<u>3- For Loza:</u>
We have time = 102.6 minutes and distance = 38 laps
<u>This means that:</u>
velocity =
= 0.37037 lap/minute
Based on the above calculations, we can note than Evans was the fastest
Hope this helps :)
