Match the expression with its
name.
9x^4-3x+4
a. quadratic monomial
b. not a polynomial
c. cubic binomial
d. fourth-degree trinomial

D. Fourth-degree trinomial

Step-by-step explanation:

I think this would be the correct answer because the highest degree the polynomial is raised to would be 4 (hence the fourth degree). It would be a trinomial because of 9x^4, 3x, and 4

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
