Combine like terms to<br> simplify the<br> expression below.<br> 5 + 2b - 2.<br> =<br> [?]b + +

muminat

Answer:

$\boxed{\sf{2b+3}}$

Step-by-step explanation:

In order to solve this problem, first you need to simplify the expression to use a distributive property.

<u>Distributive property:</u>

$\sf{A(B+C)=AB+AC}$

5+2b-2

Switch sides.

2b+5-2

Combine like terms.

You have to subtract by the numbers from left to right.

Solve.

5-2=3

<u>2b+3</u>

<u>So, the correct answer is 2b+3.</u>

I hope this helps you! Let me know if my answer is wrong or not.

If a dog drinks 8 quart of water a day, how many gallons does the dog drink in 3 days

Virty [35]

Answer:

6 gallons

Step-by-step explanation:

There are 4 quarts in gallons, so the dog drinks 2 gallons a day.

When we multiply 2 and 3, we would get 6.

So the dog drinks 6 gallons in 3 days (I don't know about you, but that's a lot of water)
