The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
y=6x-16 y=-2x+8
6x+4=52 6x=48 x=8
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
It is 8
(4, 8)
X equals to 8
8+6x = ? 8+6*5 = ? 8+30 = ?
-6
8 = -6x x = -1.3333
x=7
