Remark
Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.
Solution
(x - 7)^2 - 25 = 0 Add 25 to both sides
(x - 7)^2 - 25 + 25 = 25 Combine the left
(x - 7)^2 = 25 Take the square root of both sides.
sqrt(x - 7)^2 = sqrt(25)
x - 7 = +/- 5 Add 7 to both sides
x = 7 +/- 5
=========
x1 = 7 + 5
x1 = 12
x2 = 7 - 5
x2 = 2
Smallest x = 2
Largest x = 12
I think it’s 25.12 or C
to find circumference u multiply diameter by 3.14.
to find radius you multiply diameter by 2
diameter is 4. multiply diameter by 2 and u get 8
8 x 3.14= 25.12
For each candy bar it would be 3 dollars each so
The four candy bars are a total of 12$ it self plus the 4 dollars for the soft drink so 12+4 is 16
So 3$ each candy bar

Basically you draw the same thing on the other side of the x-axis but the b would be in the c spot and the c would be in the b spot and so on
