Question

Considering the expression x/2 + y2. Which statements are true?Mark all that apply.

A.When x=4 and y=9,the value of the expression is 37.
B.When x=12 and y= -5,the value of the expression is 61
C.When x=6 and y=7,the value of the expression is 61
D.When x=8 and y= -10, the value of the expression is 104
Plz give me a step by step explanation

Answer 1

D. 8/2 +(-10)² = 104

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
