What's the product of these binomials (x-9) (x+2)

Step-by-step explanation:

Let's find the solution, but first we need to understand the following:

multiplication of binomials establish that:

now, because your binomials are (x-9) and (x+2), using the above we obtain:

which can be simplified as:

giving the solution:

-7x-18

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

answer: sine
