Simplify. Final answers should be written in standard form. (Reminder: in order to indicate an exponent you must use the carrot (^) for example n^2 would indicate n squared). No spaces in your answer. 4(2-3w)(w^2-2w+10)

-12w^3+32w^2-136w+80

Step-by-step explanation:

4(2-3w)(w^2-2w+10)

multiply first two:

(8-12w)(w^2-2w+10)

multiply:

8w^2-16w+80-12w^3+24w^2-120w

simplify:

-12w^3+32w^2-136w+80

option: d is correct

step-by-step explanation:

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
