put a line over the 0 in the tens place.

Math Check
you should have a 8x, not 8 in your second line

mat115
determine whether or not 8^2 + 10^2 = 12^2 does 64 + 100 = 144....no so it is not a pyth triple

do you mean a perfect Pythagorean triple?

precalc
D

arithmetic
19(30) + 20= 590

trig
you should use neither...you should use 2n+1,2n+3, and 2n+5 to get odd integers

Math
distribute the 2 through the right side to get -(x-1)>2x + 1 then x+ 1 < 2X + 1 0 < X so x> 0
