Well, we know that 25% is also 1/4 and if we multiply $80.00 by 1/4 you get $20 so the answer is $20.
Answer:
C. x^2 -4
Step-by-step explanation:
What you do is subtract the functions as said by
(f-g)(x).
so:
f(x)-g(x)
(2x^2+3) - (x^2 -7)
2x^2 -x^2 +3 - 7= x^2 -4
I hope this helps you
a=4
b=9
c= -1
disctirminant =b^2-4ac
disctirminant =9^2-4.4. (-1)
disctirminant =97
x1=-9+square root of 97/2.4= -9+square root of 97/8
x2= -9-square root of 97/2.4= -9-square root of 97/8
The answer is c because k and m are the same so l and n are also the same
