Which polynomials are in standard form? choose all answers that apply:

a. 3z-1
b. 2+4x-5x^2
c. -5p^5+2p^2-3p+1
d. none of the above

A and C are the correct answers.

Step-by-step explanation:

Monomials without a variable go after the monomials with a variable. Variables with high exponents go first. A and C both show those.

In choice A, since 3z has a variable, it goes before 1. In choice C, since -5p^5 has the highest exponent it does go first. Then 2p^2, since it has the second highest exponent. Then -3p follows, with the lower exponent. Then 1 goes last because it has no variable and has the lowest exponent.

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
