I hope this helps!
pls ❤ and mark brainliest pls!
You use the FOIL method, and how you do this is -
(x - 7) (x + 8)
Multiply the first x by both numbers in the second factor. Which means, you multiply x by x and 8, the two in (x + 8).
With this, you get -
x^2 + 8x
Then do the same thing with -7.
-7x - 56
Then combine the two.
x^2 + 8x - 7x - 56
Combine like terms.
x^2 + x - 56
So now, 7 x 8 is 56
And -7 + 8 would be 1. And that is the value of “x” which is b in the form a^2x + bx + c.
Now with this, you take those two numbers and make the factors =
(x + 8) (x - 7)
Then you set these equal to 0.
x + 8 = 0
Subtract the 8 from both sides.
x = -8
————
x - 7 = 0
Add the 7 on both sides.
x = 7
Answer: A
Answer:
Step-by-step explanation:
The expression representing the amount of money that the photographer would make from selling 10 copies is given as
10(0.75p - 0.5)
where p represents the price determined for each copy. Assuming the price charged per copy is $5, then the amount made from 10 copies is
10(0.75 × 5 - 0.5) = $32.5
It could have been
10(5 - 0.5) = $45
The price is being reduced by 25%(100 - 75)
Therefore, the option that most likely describes the agreement between the online service company and the photographer is
A. The company keeps 25% of the amount paid for each copy and charges the photographer $0.50 for every copy purchased.
