X squared+y=18
x+y=6. use elimination method.(+y and +y cancels
x squared -x=x
18-6=12
x=12
for y take one of the above equations
x+y=6(replace x with 12
12+y=6(collect the like terms
y=6-12
y=-6
so x=12 and y=-6
Answer:
h=4
Step-by-step explanation:
a^2 = h^2 + 4
b^2 = h^2 + 64
(2 + 8 )^2 = a^2 + b^2
100 = h^2 + 4 + h^2 + 64
100-68 = 2h^2
32 = h^2
h = 4
