Could someone help me?

1.(x−6)(x−9)

2.2(x2−14x+15)

3.x2−18x+88

Step-by-step explanation:

here explain

The middle number is -15 and the last number is 54.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -15

Multiply together to get 54

Can you think of the two numbers?

Try -6 and -9:

-6+-9 = -15

-6*-9 = 54

Fill in the blanks in

(x+_)(x+_)

with -6 and -9 to get...

(x-6)(x-9)

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
