Question

Help please. Tell wether the expressions in each pair are equivalent
A. 5x • 1 and 1 + 5x
B. 1 + (2t + 1) and 2 + 2t

Answer 1

A) is not equivalent
B) is equivalent

Answer 2

B) 1+(2t+1) and 2+2t are equivalent because if you distribute 1+(2t+1) you get 1+2t+1 so just add the 1's together and you get 2t+2 which is the same as 2+2t
It's just flipped
