Which expression is equivalent to 7 (a+2) when a=6?

7 (6)

9 (6)

7 (6) + 2

7 (6) + 14

7 (6) + 14

This could be seen as the answer because the 7 has already been distributed to the two which is just 7*2 which is 14. The problem then gives you what a equals so 7 (6) + 14 would still equal out as if it were 7 (6+2).

For a better explanation you could see that 7 (6) + 14 simplifies ti 42+14 which then equates to 56. You can the. Do the given expression 7 (6+2) and simplify and get 7 (8) then multiply and you'll get 56 once again.

It is equivalent to 7 (6) + 14

Step-by-step explanation:

Step 1: Solve 7 (a + 2) when a = 6

⇒ 7 (6 + 2) = 7 * 8 = 56

Step 2: Find its equivalent

7 (6) + 14 = 42 + 14 = 56
