Those are the answers
2x-2
6x+9
7x+35
10x-5y
A is c=75 B is a=120 C is b= square root of 75 and D= square root of 245
1) is 9
2) is 2
Absolute value of a number is the distance a number is from 0.
The "distance formula" an extension of the Pythagorean Theorem is:
d^2=(x2-x1)^2+(y2-y1)^2 in this case:
d^2=(-8-7)^2+(-9--1)^2
d^2=(-15)^2+(-8)^2
d^2=15^2+8^2
d=√(15^2+8^2)
So the answer is 15^2+8^2
