A product is the answer that you get when you multiply numbers together. So for this problem, you have 2 groups to multiply together. Since I cannot show a square or cubed x, I will put an x2 for x squared and an x3 for x cubed. You have to multiply each number in the first parentheses by each number in the second parentheses. Then combine any like sets.
(8x-3)(x2-4x+8)
8x3-32x2+64x-6x+12x-24
8x3-32x2+70x-24
So the answer is 8x cubed minus 32x squared plus 70x minus 24. Whew! That's a long one. Hope I didn't miss anything.

Answer:
A
Step-by-step explanation:
You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.
1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r
Answer:
<h2>
The answer is A</h2><h2>A. S = 1/2p - L</h2>
Step-by-step explanation:
Step one:
given the perimeter function
P = 2S + 2L
we are expected in this problem to change the subject of the formula to S
Step two:
firstly, let us isolate the term that has S
2S=P-2L
divide both sides by 2
2S/2= (P-2L)/2
S=P/2-L
S = 1/2p - L
