x=12 because 12 over 6 is 2,and 2 plus 4 is 6.
x = 2
If: x+2 = y+6 Then: y = x-4
x + 6 = -2 Therefore, x = -2 - 6 x = -8
6 x 2 + 6 + 18
6, 2
4
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
2x = 4 x = 2 Try it out
x (x+5) = 6 X equals 1.
x = -2 and y = 4 (-2,4)
(x+5)(x+6) equals x^2 +11x+30
