Combine like terms. what is a simpler form of the expression
-3(-4y+3)+7y

For this case we must simplify the following expression:

We apply distributive property to the terms within parentheses taking into account that:

So:

We add similar terms and finally we have:

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
