Question

Which is NOT equivalent to this expression?

3(5g² + 15g)
whats the answer?
a) 15g² + 45g
b) 15g (g + 3)
c) 15(g² + 3g)
d) 15g² + 15g

Answer 1

The answer will be D

Answer 2

D. (15g² + 15g) is not equivalent to the expression because although the first part is right 15g² the second part isn't correct because 3 times 15g equals 45g not 15g. All the rest are equivalent. Hope this helps!
