x - 8 + x - 5 + x + 1 = 3x - 12
8 + 3 x 5 = 23
If you mean: x+8-x+9 when x = 5 Then it is: 5+8-5+9 = 17
-3
8(x+5) is equivalent to 8x+40
x - 8 + x - 5 + x + 1 = 3x - 12
(x + 5)(x + 8)
8 + 3 x 5 = 23
If you mean: x+8-x+9 when x = 5 Then it is: 5+8-5+9 = 17
5 + 8(3 + x) 5 + 24 + 8x 29 + 8x
-3
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
13
8(x+5) is equivalent to 8x+40
x = 8
Substitute 5 for x and solve: 8 + 6(5) = ?
x(x + 8)(x + 5)
