I think it’s 0 bc it’s the only one that isn’t negative
Answer:
Step-by-step explanation:
1) She solved the first equation for x:

2) Plug x into the second equation:

3) Plug y into the first equation to find x:

Complete the interval: (2, -2)
Basically just multiply the sides that are the same so 12 x 12 and than 8x8 Than 2x2 and what I get I think u add them all together
X+8 = 13
subtract 8 from both sides
x= 5

6/x = x/12
x^2 = 72
x = √72
x = 6√2
y^2 = 12^2 + (√72)^2
y^2 = 144 + 72
y^2 = 216
y = 6√6
21)
14 - 8 = 6
y/8 = 6/y
y^2 = 48
y = √48
y = 4√3
x^2 = 6^2 +(√48)^2
x^2 = 36 + 48
x^2 = 84
x = √84
x = 2√21
