Write an equation for the number of dollars, d, that you pay for your karate classes if you take classes for m months.
I am assuming the cost is 80 dollars per month
d = 80m
The formula for the circumference of a circle of radius r is C = 2pi*r.
Here we know that the circumference is 42 inches, and we need to find the radius, r. Solving this equation for r, we get:
42 inches
r = ------------------ = 6.68 inches, to the nearest hundredth.

Answer:
x=1, 5
Step-by-step explanation:
0 = 4(x - 3)^2 - 16
Add 16 to each side
0+16 = 4(x - 3)^2 - 16+16
16 = 4(x - 3)^2
Divide each side by 4
16/4 = (x-3)^2
4 = (x-3)^2
Take the square root of each side
±sqrt(4) = sqrt( (x-3)^2)
±2 = (x-3)
Add 3 to each side
3±2 = x-3+3
3+2 =x so x=5
3-2 =x so x=1
