It’s not possible if that’s kne of the options
A. C(n)=10n+125
cost×number of buttons is equal to 10 cents times the number of buttons, plus the $125 cost of the button machine
The answer is -10 x -9, -8, -7, -6 etc
The answer is A. After you square root both sides, you have to add 3 to both sides and then divide both sides by 4.
Base = x
height = x-4
Area = .5 * height * base
48 = .5 * (x-4) * x
96 = x^2 -4x
x^2 -4x -96=0
x = 12
base = 12
height = 8
