2(3b+6b+2b)???

Question

FIRST RIght ANSWER GETS 10 POINTS

3n+2n = 45

how did u do that?

Answer 1

22b

Answer 2

2 (3B + 6B + 2B) = Y

Solve for Y

2 * 3B + 2* 6B + 2 * 2B = Y
6B + 12B + 4B = Y
22B = Y

or 22B / 22 = 1 /22

B = 1/22

This is no way to do your home work you will need the knowledge later.

3n+2n = 45

Solve for N

5N = 45
5N / 5 = 45 / 5
N = 9

Answer 3

3b+6b+2b = 11b and multiply by 2. You get 22b.

3n+2n = 45
5n =45
n = 45/5
n=9

Instead of keep posting up questions, you can IM me and maybe I can help you more.

Answer 4

2(3b+6b+2b) =
(2 x 3b) +( 2 x 6b) + (2 x 2b) =
6b+12b +4b=
22b

Try the method I just used and see what you get for the second question. You should get 5n

Answer 5

2(3b + 6b + 2b)

Preform the parenthesis first

2(11b)

the sum of 3b + 6b +2b) = 11b

22b

Multiply 2 x 11b = 22b

The answer is 22b

The solution set is {22b}

Answer 6

The answer is 22b

2(3b+6b+2b)
2x3b=6b;2bx6=12b;2x2b=4b
6b+12b+4b=22b

Answer 7

3n+2n=45
5n=45
5/5n=45/5
n=9

2(3b+6b+2b)
2(11b)
22b=?
b= -22

Answer 8

6b+12b+4b= 22b

3n+2n = 45

5n = 45
n = 9

Answer 9

.. 2(3b+6b+2b)
= 6b + 12b + 4b .. take the brackets off
= 22b .. add them all

---------------------------
3n+2n = 45
5n = 45
n = 9

Answer 10

2(3b+6b+2b)
=6b+12b+4b
=22b

Answer 11

6b+12b+4b=22b
