Answer:
Prime.
Step-by-step explanation:

First let's multiply our outer coefficients in this case 1 and 8, so we have 1x8=8. Now the point of this is to get the factors of 8 and see if we can get that middle term -7. Factors of 8 are 1x8, 2x4 and that's it. From there I notice that -8+1 = -7 and so:

Notice that the (x-8) and (x+8) are not the same factors, therefore the factors are not any of those answer choices and so it's prime. You can calculate the factors by using the quadratic formula, however I think that is beyond the scope of this question.
So you want to know how many times

fits inside

, if so, here's the answer:
First we see that

is equal to <span>4,000,000, and</span>

is equal to 10,000.
Then we divide

, and we get 400, so.
The answer is 400.

Answer:
y = 20x + 25
Step-by-step explanation:
y is the total
25 dollars to start plus the 20 dollars per month
The coordinates would be (-3,-1)
A = L * W
A = 75
L = W + 10
75 = W(W + 10)
75 = W^2 + 10W
W^2 + 10W - 75 = 0
(W + 15)(W - 5) = 0
W + 15 = 0
W = -15...not this one because it is negative
W - 5 = 0
W = 5 <=== width is 5 ft
L = W + 10
L = 5 + 10
L = 15 <=== length is 15 ft
