The expression IS 5*4 - 8.
8 + x 40 is not a valid mathematical expression.
The expression X/(X+8) is undefined at X=-8, because that would be division by zero.
-(x+3) is one possible answer.
(x-8)(x+8)
69 is an equivalent expression.
8⁴ = 8x8x8x8 = 4096
It is: 7*(8*15) = 840
82y 16x are both not equal to the given expression.
Let the number be x and so the expression is: x-19
21
40 + 32 = (5 x 8) + (4 x 8) = 9 x 8 = 72

The expression IS 5*4 - 8.
It is: 9*(8+1) = 81
Yes, -6+x is the same as x-6.
