The formula for the area of a trapezoid is:
A= (a+b)/2*h
A=150
h=10
b=14
a=?
So we need to solve for a. Let's plug in the values that we do know...
A= (a+b)/2*h
150=(a+14)/2*10
150=(a/2+14/2)*10
150=(a/2+7)*10
Divide both sides by 10
15=a/2+7
subtract 7 from both sides
8=a/2
multiply both sides by 2
16=a
The other base is 16

What are we supposed to find
Answer:
He did the complete opposite of what he needed to do
Step-by-step explanation:
The error is that when you need to find x - intercept, you need to replace the value of y with zero, not the y value.
Cause otherwise, what he did here is to find the y - intercept

Answer: 
Step-by-step explanation:
In order to solve this exercise you need to analize the information provided.
Notice that , according to the exercise, Sheila has to run a total of 5 kilometers to finish the race.
You know that the distance Sheila has run in 10 minutes is 1.875 kilometers.
Then, knowing the above, you need to subtract the total lenght of the race (5 kilometers) and the distance she has already run (1.875 kilometers) in order to calculate how much farther Sheila has to run to finish the race.
Therefore, you get the following result:
