Question

Suzanne says the two expressions 2(3a – 2) + 4a and 2(5a – 2) are equivalent? Is she correct? Explain why or why not?

Answer 1

Answer:

Suzanne is incorrect.

Step-by-step explanation:

To figure out if the two equations are equivalent, we can simplify each one of them.

Simplifying the first equation, we get:

$2(3a-2)\\6a-4$

Simplifying the second equation, we get:

$2(5a-2)\\10a-4$

Now that both equations are simplified, we can see that the equations are not equivalent. Suzanne is incorrect.
