If x+y=10 and x-y=4, find the value of x2+y2

x+y+x-y=10+4

2x=14

x=7

7-y=4

y=11

put the value x and y of in x^2+y^2

16+121=137

mark it as brainliest

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
