So the way to figure out the sides of a right triangle, is basically
A^2 + B^2 = C^2
Letter A is the only one that would work, because the first number squared (times itself), added to the second number squared, would equal the third number squared. This is a basic principle of the pythagorean theorem, which I can explain in more detail if you'd like. :)
Just did one just like it
688.32 = x + .043 x + .0325 x = 1.0755 x
x = 688.32/1.0755 = $640.00
Answer: $640.00
Check: 640(1+.043+.0325)= 688.32 good
-5a^2 - 7a = -a x (5a + 7)
let me know if you have any other questions

the diameter of two tortillas would be 6, since 12+12=24. the diameter of 24 is 6, so that would be your answer....
