What's the polynomial of (5x+5)(8x+5) ? plz

Hey! I have been helping you out with a bunch of these questions so I think it is time you try a bit of it on your own.

Remember do the left side of the () multiplied by the left side of the other () first.

(5x * 8x)

Then the left side of the first () multiplied by the right side of the right ().

(5x * 5)

Then the right side of the left () multiplied by the left side of the right ().

(5 * 8x)

And then do the right side of both () multiplied together.

(5 * 5)

Then combine like terms and you have your answer. If you need help comment on this. :)

Iam guessing c. or d.
