I need some help with my Algebra problems. Please help!

1. solve: (x+4)(x-4)(x+3)>0 - The solution set is {?}.

2. solve sgrt7x+46 = x+4 - Use a comma to seperate answers. The solution is?

3. solve for x. 4x(x-1)-5x(x)=3 x=? Use a comma to seperate answers.

4. factor comepletely. 6x^8-12x^7+42x^6. The complete factorization is? Answer in a factored form.

5. Add. (2x^2-2xy+y^2)+(-7x^2-9xy-y^2)+(x^2+xy-9y^2)

6. Multiply. (3 sqrt3 -9 sqrt7)(4 sqrt3 +12 sqrt7) an exact answer, using radicals as needed.

7. multiply and simplify. Assume variables represent non-zero real numbers. x^17 * x^0=? answer with exponential notation with possitive exponents.

8. Divide. (28b^3+27b^2+22b+43) divided by (4b+5).

9. Simplify by taking roots of the numerator and the denominator. Assume that all expressions under radicals represent positive numbers. 3sqrt8x^11/y^3 use radicals as needed.

10. find a polynomial for the perimeter and for the area. x+10 (top), x is side. The perimiter & area are?
