Tommy thinks the two expressions below are equivalent -3 (6a - 5) + 4a and
22a + 15
A) Is he correct?
B) Explain why or why not?

no, they are not equivalent expressions

Step-by-step explanation:

simplify: -3(6a - 5) + 4a = -3(6a) + (-3)(-5) + 4a  =  -18a + 15 + 4a  =  -14a + 15

-14a + 15 ≠ 22a + 15

town b, median - q2 = 25
