Question

Simplify 3(2x + 5)
A. 6x + 30
B.6x + 15
C. 6x + 5

Answer 1

The answer is B. 6x+15

Explanation:

You must follow the Mnemonic PEMDAS which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Also the distribution property applies here.

Since, you have a parentheses, you will distribute the 3 by multiplying 3 times 2x, which will give you 6x. Next, you distribute the 3 again and multiply it by 5, which will give you a value of 15.

Due to 15 being a positive number, the answer will be 6x+15.
