Answer:
D. 8/2 +(-10)² = 104
Step-by-step explanation:
To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.
The respective expression values are ...
A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83
B 31 ≠ 61
C 52 ≠ 61
D 104 =104 . . . . true statement

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.
Answer:
C. Sqrt(12^2+9^2)
Step-by-step explanation:
Pythagorean theorem is
x^2+y^2=z^2
So solving for z
z=sqrt(x^2+y^2)
z=sqrt(9^2+12^2)
