I would really appreciate help on these equations.

4. to find what x is just do this:

x-2=4

x+1=4

solve for those and you should get 2 answers

Not sure about 7.

3. |D-30| < 3

D = 27 < D < 33

(< should actually be <or=, but I can't type it)

4. x^2 -x -2 = 4

x^2 -x -6 = 0

(x-3)(x+2) = 0

x = 3 or -2

7. 2x(x^3 +8)
