Express (x-5)^2 as a trinomial in standard form. whoever can help me gets brainlest and 20 points please hurry.

i think the answer is b.

step-by-step explanation:

not 100% sure though.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

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).

32.5 is the answer i got thats the answer
