Which of the following expressions can be written as 12(a + b)? a.(12 + a) ∙ (12 + b)
b.12a + 12b
c.(12 + a) + (12 + b)
d.12a ∙ 12b

12a + 12b

Step-by-step explanation: Use the distributive property. The property is that you can take the 12 and multiply it by both letters inside separately.

12(a+b) = (12 * a)+(12 * b) = 12a+12b

It's easier to see a picture of how the distributive property works.
