Simplify the product using FOIL. (2x – 7)(5x + 5)

10x - 25x - 35

Step-by-step explanation:

F 2x times 5x = 10x

O 2x times 5 = 10x

I  -7 times 5x = -35x

L -7 times 5 = -35

Hope This Helps :)

10x^2-25x-35

Explained:

(2x)(5x)=10x^2

(-7)(5)=-35

(-7)(5x)=-35x

(2x)(5)=10x

10x-35x=-25x

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

9 x 8 divided by (5-3)=36
