Answer:

Polynomials are always closed under multiplication. Unlike with addition and subtraction, both the coefficients and exponents can change. The variables and coefficients will automatically fit in a polynomial. When there are exponents in a multiplication problem, they are added, so they will also fit in a polynomial.

Answer is A. 18

EXPLANATION-

Its Simplifying
(9x + -44) = (6x + 10)

Reorder the terms:
(-44 + 9x) = (6x + 10)

Remove parenthesis around (-44 + 9x)
-44 + 9x = (6x + 10)

Reorder the terms:
-44 + 9x = (10 + 6x)

Remove parenthesis around (10 + 6x)
-44 + 9x = 10 + 6x

Solving
-44 + 9x = 10 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.
-44 + 9x + -6x = 10 + 6x + -6x

Combine like terms: 9x + -6x = 3x
-44 + 3x = 10 + 6x + -6x

Combine like terms: 6x + -6x = 0
-44 + 3x = 10 + 0
-44 + 3x = 10

Add '44' to each side of the equation.
-44 + 44 + 3x = 10 + 44

Combine like terms: -44 + 44 = 0
0 + 3x = 10 + 44
3x = 10 + 44

Combine like terms: 10 + 44 = 54
3x = 54

Divide each side by '3'.
x = 18

Simplifying
x = 18
