Answer: (f-g)(x) is equivalent to f(x) - g(x)
So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3
Hope this helps.

There are 23 nickles in her purse
Answer:
27 of the pets are dogs.
Step-by-step explanation:
Real easy way to do this, treat 45 (the total) as 100. So, do 45/100 then multiply the result of that by 60, and you end up with 27.
45/100=0.45
0.45*60=27
(x + 8)(y + 3)
x*(y+3) + 8*(y + 3)
x*y + 3*x + 8*y + 3*8
xy + 3x + 8y + 24
So the correct product is = xy + 3x + 8y + 24, I guess the second expression.
I hope this helps.
