Let the number be x and so the expression is 8x
8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
8(30) - 40 = 240 - 40 = 200.
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.

8(x + 1)
Let the number be x and so the expression is 8x
To simplify the expression 8x - 8 - 4x - 3 - 3x, first combine like terms. Start by combining the x terms: 8x - 4x - 3x = x. Then, combine the constant terms: -8 - 3 = -11. Therefore, the simplified expression is x - 11.
abs(8x - 7)
It is: 29+8x
8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
x * -8 = -8x
8x + x = 9x
8(30) - 40 = 240 - 40 = 200.
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
It is difficult to tell what expression you are trying to convey. 8 multiplied by x, and then take y away, is 8x-y x take away y, and then 8 multiplied by this number, is 8(x-y) 8 multiplied by x, and divided by y is 8x/y
x2 + 8x = x(x+8)
