Answer:
3 is a right angle
Step-by-step explanation:
We know there are no squares between 100² and 101².
So we just want to know how many numbers between a and b exclusive, which is
n = b - a - 1
For example between 10 and 20 exclusive we get n=20-10-1=9, which is right.
For our problem here we can factor using the difference of two squares and get:
n = 101² - 100² - 1 = (101 - 100)(101 + 100) - 1 = 1(201) - 1 = 200
Answer: d. 200

You can get this my multiplying the scale factor by the height. In this case you need to use the bottom number to multiply since you are going in reverse.
-50 and -18 multiplied together equal 900 and added together equal -68 because a - times a- equals a positive.
A = 3. Hope this helps! (Was trying to show the work but I can't take pictures at the moment.)
