Answer:
52
Step-by-step explanation:
(-6)x(-6)=36
(4)x(4)=16
36+16=52
Answer:
x = 6 x 6
y = 4 x 4
Step-by-step explanation:
<em>This is because...</em>
x^2 means "x cubed", meaning multiply it by itself. Same for y.
<em>Now the math...</em>
6 x 6 = 36
4 x 4 = 16
<em>Math 2</em>
Without rounding, we find the true sum of 36 + 16 = 52.
Therefore,
x^2 + y^2 = 52
