Answer:
73
Explanation
To find the average we need to find the mean. So you have
87,93,96, and 89. Add it up and you get 365. Next you have to divide it by how many numbers there are, so 365 divided by 5 and you get 73.
(I divided 365 by 5 because we are looking for the score she needs on the 5th quiz too.)

b. 2x + 6 represents how to find the area of the table cloth.
c. 2x represents the x length getting multiplied by 2, since there are 2 sides.
