What two numbers add up to -1 and multiply to -72?

-9 and 8

Rewrite the expression above

(x - 9)(x + 8)

y=mx+b

step-by-step explanation:

m slope

b y-intercept

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
