It should be 7 wouldnt it be
Answer:
a
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
Basically to solve this, you set both equations equal to each other and solve because the angles are the same.
5x+7=8x-71
isolate x by adding 71 to both sides and subtracting 5x from both sides
3x= 78
divide 78 by 3
x=26
