Answer 1

I can't possibly do all of your homework for you, that's a ton of problems and is obviously a large part of your homework.

I'll help you if you don't understand, though..

*Simplify if Possible*

9. You can simplify this. Just multiply all of the terms and you should get:

35x^2

14. Just combine like terms. That's all.

*Solve*

16. k - 1 = -11

Well, move -1 to the other side and you'll get:

k = -10

21. 3x + 6 = 12

Get 6 on the other side.

3x = 6

Divide the whole equation by 3.

x = 2

Most of them are like this. Just do them the same way I showed you.

Answer 2

I did end all of mine. I had to do this super undertaking which contains an essay approximately if i presumed baseball gamers have been paid too lots. It took especially lots the great afternoon. Then I had to accomplish a little evaluate worksheets for historic previous AND memorize all the presidents so as. Argh, i'm happy it particularly is over with by way of fact I have not got any homework today :)

Answer 3

alright lemme show ya the steps to one maybe you can do the rest yourself kay?
16. 1k-1=-11 write out problem, put a 1 one infront of k because theres one k there.
+1 +1 add one to each side to isolate variable.
1k=- 10 divide both sides by one
k=-10 then pug in your numbers 2 check answer

Answer 4

9. 35x^2
