Take half of the middle coefficient.
Then square it.
-12/2 = -6
(-6)^2 = 36
c = 36
Answer:
6
Step-by-step explanation:
If two sides of a right triangle are x and y, the hypotenuse, h is:
h^2=x^2+y^2, in this case x and y are 39 and 52 respectively so:
h^2=39^2+52^2
h^2=1521+2704
h^2=4225
h=√4225
h=65 in
So the hypotenuse is 65 inches.
The sum of 4.35 and -5.66
