How do I do this math?

2. theorem of Pythagoras

r²=x²+y²

r²=6²+8²

r²=36+64

r²=100square

r=10

therefore x=10

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
