Question 1

1.

Select all (and only) monomials of degree 4.

8(ab)^{4}

9xy^{3}

4x^{2}y^{3}

-3h^{4}j^{2}

\frac{2}{7}x^{4}

Question 3

3.

Choose the option that meets all three requirements:
The expression is equivalent to 8h^{2}-3h^{2}k^{3}+20h^{3}k-5+12k-6h^{2}
The expression is in standard form
All like terms have been combined

-3h^{2}k^{3}+20h^{3}k+8h^{2}-6h^{2}+12k-5

-5+12k+2h^{2}+17h^{2}k^{3}

17h^{2}k^{3}+2h^{2}+12k-5

-3h^{2}k^{3}+20h^{3}k+2h^{2}+12k-5

Question 4

4.

Simplify the expression. Make sure your answer is in standard form for a polynomial.

(2x^{2}+6x+5)-(3x^{2}-2x+1)

Question 5

5.

Simplify the expression. Make sure your answer is in standard form for a polynomial.

(15x^{3} – 6x – 23) + (3x^{3} – 5x^{2} + 8x + 10) + (-8x^{3} + 2x^{2} – 7x) + (9x^{2} – 4x + 15)
