Simplify the expression
5x+2(x+6)
A. 7x+6
B. 7x^2+12
C. 7x+12
D. 7x(x+6)
Is the answer C?
The answer is C.
To simplify the expression 5x + 2(x + 6), we need to apply the distributive property, which states that multiplying a term by a sum is equal to multiplying the term by each individual term in the sum and then adding the results.
First, let's distribute the 2 to the terms inside the parentheses:
5x + 2(x + 6)
= 5x + 2x + 12
Next, combine like terms by adding the coefficients of the x terms:
= 7x + 12
Therefore, the simplified expression is 7x + 12. So the correct answer is indeed C.
