Question

Which expression is equivalent to 5x + 5y − 2z? Which property justifies the expressions being equivalent?

A) 5(x + y) − 2z; distributive property
B) 5(x + y − 2z); distributive property
C) 8xyz; subtraction property
D) 10xy − 2z: associative property

Answer 1

A) -4z^3+4z^2+6z+35

Explanation:

Answer 2

5(x + y) − 2z; Distributive Property

Explanation:

The coefficient for both 5x and 5y is 5; therefore, use the distributive property to rewrite the sum as 5(x + y).
