Question

Which expression is equivalent to 7(a+2) when a=6? 7(6) 9(6) 7(6)+2 7(6)+14

Answer 1

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.

Answer 2

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
