What is the value of -3(15-s)+2s^2 when s=-3
PLEASE ANSWER QUICKLY

-36

Step-by-step explanation:

1. Plug -3 into the equation given: -3(15-(-3)+2(-3)^2

2. Use Pemdas and first distribute the negative to negative three then distribute -3 to the rest of the parenthesis (final answer): -45-9 +2(-3)^2

3. Then put -3 to the power of 2 (which is 9) then multiply it by 2 (final answer): -45-9+18

4. Combine all like terms and you get the answer -36!

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
