13 points! Multiply each and write in standard form. 1-8 you do not have to give explanation but it would help. Brainiest to first answerer.

1.

(y - 2)(y - 4)

Multiply all terms on the right with y, then do the same with -2

Multiply y by y:

Then y by -4:

Then -2 by y:

Then -2 by -4:

We already have first, then and finally , so we don't have to rearrange anything.

2.

Multiply all terms on the right with 6y^2:

Not sure which order is preferred here, you can put either the term first or .

3.

Multiply all terms in the right parenthesis with 2x^4 :

4.

First, multiply all terms on the right with 7x. Then do the same with 3.

5.

Multiply all terms on the right with 3x, then do the same with 4y:

Here, I choose to rearrange them to x^2, then y^2, then xy:

6.

Like previous similar ones, we multiply all terms in the parenthesis with -5x^6:

7.

Multiply all terms in the right parenthesis with -x^2y:

Here, you can also choose which order you believe is appropriate.

8.

Multiply the terms on the right with 7x, then with -3y:

depends on how many days you are talking about
