8x^4
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
(4x2) (x/4)(8x - 32) =x3(8x - 32) = 8x3(x - 4)
8 times 3 plus 32 equals 56. 8x + 32 = 56 8x + 32 - 32 = 56 - 32 8x = 24 8x / 8 = 24 / 8 x = 3
15
It is -8x.
I is -8x^2.
Following the correct order of operations, 8x + (1)(121) - (x/6x)(9)-x=8x+121-1.5-x=7x+119.5
8x + 15 = 7 so 8x = 7 - 15: x = -1
(-8x)+9=7 -8x=-2 x=1/4
Eight times whatever the value of x is.
