 Question 344438: A triangle has a side of length x . The second side of the triangle is 2 inches longer than the first side. The third side is 4 inches longer than the first side. The square of the first side plus the square of the second side is equal to the square of the third side. What is the length if each side of the triangle? USE THE 5-STEP METHOD. This is how much I've figured out so far: x²+(x+2)²=(x+4)² x²+x²+2x+2x+4 = x²+4x+4x+16 x(4)+4+4 = x²+8x+16 -4x -4x x(4)+4 = x² +4x+16 x(4)+4-4 = x²+4x+16-4 x(4) = x²+4x+12 -x² = -x² So if x²=4x+12, SOLVE FOR X. I think the answer is 6, but I don't know the procedure. I.E, x=5 x=6 25=20+12 36=24+12 25=32 36=36 6²+8²+10² 36+64 =100 x=6 I need help ASAP, please!!!
