Question

Combine the like terms to simplify the expression: 9+3+17xy(2)+8y(3)+10x –13xy(2) – 9x – 6y(3)

a. 2y(3)+4xy(2)+x+12
b. 2y(3)+4xy(2)+10x+9
c. 2y(3) – 4xy(2) – 3x+12
d. 2y(6)+4x2y(2)+10x+12 THE NUMBERS IN THE PARENTHESIS ARE EXPONENTS

Answer 1

9 + 3 + 17xy² + 8y³ + 10x - 13xy² - 9x - 6y³
12 + 17xy² + 8y³ + 10x - 13xy² - 9x - 6y³
17xy² - 13xy² + 10x - 9x + 8y³ - 6y³ + 12
4xy² + x + 2y³ + 12

The answer is A.
