Question

Find the sum 6y sqrt a +7y sqrt a

Answer 1

D.) 13y sqrt a

Explanation:

Answer 2

For this case we must add the terms of the following expression:

`6y \sqrt {a} + 7y \sqrt {a}`

It is noted that the terms are similar, so we can add:

We take common factor
`\sqrt {a}:`

`\sqrt {a} (6y + 7y) =`

We add the terms within the parenthesis:

`\sqrt {a} (13y) =`

finally we have:

`13y \sqrt {a}`

Answer:

`13y \sqrt {a}`
