30a + (6a*d)

Explanation:

Hope you ace your test!

Answer 2

first, second and fourth

Explanation:

If you use distribution,

6a(5+d) is the same as

6a(5) + 6a(d)

Multiplied = 30a + 6ad

So it's the 1st 2nd and fourth choice.

1st is stated above when multiplied out and combined.

2nd is after distribution.

4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.

It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.

It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)
