Answer:

We have to prove that,

-2(x+1)=8, then x= -5

L.H.S.

-2(x+1)=8

By distributive property,

-2x-2=8

Adding 2 both sides ( Additive property of equality )

-2x-2+2=8+2

-2x=10

Divide both sides by -2 ( Division property of equality ),

\frac{-2x}{-2}=\frac{10}{-2}

x=-5

= R. H. S

Hence, proved....

Step-by-step explanation:

distribute the -2 to (x+1) you end up with -2x-2=8 (multiplication property). Add 2 to both sides to get rid of the -2 of the left (addition property). 8+2=10. -2x=10 divide the -2 to both sides. x=-5 (division property).

Given:

Minni is arranging 3 different music CDs in a row on a shelf.

To find:

The sample space for the arrangement of a jazz CD (J), a pop CD (P), and a rock CD (R).

Solution:

We know that the total number of ways to arrange n items is n!.

Minni is arranging 3 different music CDs in a row on a shelf. So, the total number of ways is:

3!=3\times 2\times 1

3!=6

The sample space for the arrangement of a jazz CD (J), a pop CD (P), and a rock CD (R) is:

{JPR, JRP, PJR, PRJ, RJP, RPJ}

Therefore, the required sample space is {JPR, JRP, PJR, PRJ, RJP, RPJ}.

Hello!  I would be happy to help you with your math problem.  For this problem, we plug in the values until we find what fits.  In this case, we have to find what is true, or, in other words, equals 37.

The answer to your question would be B -- -3.  Here is why.

-15*-3-8=37.

Hope this helps!
