Answer:
x=0 y=-3
Step-by-step explanation:
19)
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
2. |2+(-4)| = 2 |2| + |(-4)| = 6
X+5/2-x+3/6=1
make the fractions have the same denominator
x+15/6-x+3/6=1
18/6=1
3=1 so the equation is not true
