Question

which expression is not equivalent to the other expressions?
7 + 0.5 x 4^2
2.5 x (16-2^2)
(3^3 + 3) ÷ 2
20 + 5^2) ÷ 3

Answer 1

The first one is 7 + 0.5*16, which = 7 + 8 which = 15.
The second one is 2.5*(14^2) which is over 400, way off.
The third one is (27+3)/2, which = 30/2, which is 15.
he last one is (20 + 25)/3, which = 45/3, which equals 15. So the answer is the second one :) Hope that helped!
