Answer 1

Yeah I'm sorry I didn't see you there. I deleted it tho, carry on. :)

Answer 2

what chib?

Answer 3

Thank you :3

Answer 4

All you have to do is distribute the -5 and the 2 into the parenthesis.

For -5, we multiply it by x and by -3.

-5(x - 3)
-5x + 15

and now for 2 we do the same:

2(a - 9)
2a - 18

Now we put them together:

-5x + 15 + 2a - 18

Now we just add like terms:

+15 - 18

-3

And our final answer is: -5x + 2a - 3

The answer is C

Answer 5

Answer 10

Simplify: –6(x – 3) – 4(y + 5) + (–5)(7 – 2b)

A.
–6x –4y – 10b – 3

B.
–6x –4y + 10b – 37

C.
–6x –4y + 10b + 3

D.
–6x –4y + 10b + 33

Answer 11

Well the first thing we notice is the +(-5). This just cancels out to -5 so we have:

–6(x – 3) – 4(y + 5) – 5(7 – 2b)

Now lets move from left to right. We do the same as before but with the -6 first:

-6(x - 3)
-6x + 18

Now we have: –6x + 18 – 4(y + 5) – 5(7 – 2b)

Now we can distribute the -4:
-4(y + 5)
-4y - 20

Now we have: –6x + 18 – 4y - 20 – 5(7 – 2b)

We now do the same with -5:

-5(7 - 2b)
-35 -10b

Now we have: –6x + 18 – 4y - 20 – 35 - 10b

All that is left is to mix like terms:

18 - 20
-2

Now we have: –6x – 4y – 35 - 10b - 2

Answer 12

I think I did something wrong, hold on.

Answer 13

Oh, I didn't add the -35 and -2.

Answer 14

The answer is B. –6x –4y + 10b – 37
