To begin solving this system of linear equations by elimination, you can add the equations.

3x + 2y - 38
5x - 2y = -30
8x = 8
This step works because of the
A. distributive property
B. commutative property
c. multiplication property of equality
D. addition property of equality

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
