Answer:
x>8 and x<6
Step-by-step explanation:
well first the values of x-7 have to be greater than 1 or, less than -1
because if x-7=-2 then |-2|=2>1 satisfying the equation
so we have

and we have

to graph it it goes from (-∞,6)∪(8,∞)
Step-by-step explanation:
x^3 is a perfect cube, 8 is a perfect cube, so we use difference of cubes.

Cube root of x^3 is x.
Cube root of 8 is 2
So
a=x
b= 2.

Set these equations equal to zero



If we do the discriminant, we get a negative answer so we would have two imaginary solutions,
Thus the only real root is 2.
If you want imaginary solutions, apply the quadratic formula.

and

Answer: 57r + 42
Step by step explanation:
-3r - 6(-7 - 10r)
Distribute -6 through the parenthesis
-3r + 42 + 60r
Collect the like terms
57r + 42
