Question

teresa says the two expressions below are equivalent: 2(5x-3) + 6x and 16x -3 is teresa correct? Explain why or why not

Answer 1

No.

Explanation:

2(5x-3) + 6x is equal to 16x-6:

Distribute:

=(2)(5x)+(2)(−3)+6x

=10x+−6+6x

Combine Like Terms:

=10x+−6+6x

=(10x+6x)+(−6)

=16x+−6,

Which is not equal to 16x-3
