The correct answer is:
Step-by-step explanation:
Given expression is:
We can combine terms as:
Any term that is added to an expression is also subtracted from the expression
So,
As b = 3 so (b)^2 will be added and subtracted in the expression
Hence,
The correct answer is:

First, I will explain it.
1. Multiply the #s inside the parenthesis Distributive Property.
It now looks like this: 5x-15-2x-2=4
2. Add like terms.
It now looks like this: 3x-17=4
3. Isolate the variable x.
It now looks like this: 3x=21
4. Now solve for x.
The answer is D, x=7.
(p.s. I won't give a stranger my number.)
Answer:
22.2 pounds and 1g = 7.4p
Step-by-step explanation:
Lets go in an inverse sense, finding firstly the constant variation and then the weight of 3 gallons.
The constant variation is the relation between gallons of diesel volume and pounds of diesel weight. For thise we would like to find how many pounds of diesel weights 1 gallon. We have the following equality:
5 gallons = 37 pounds
Now, lets divide both sided by 5, as we know the equality will still:
5/5 gallon = 37/ 5 pounds
1 gallon = 7.4 pounds
So, this is the constant variations: every extra gallons weights 7.4 pounds. We could also do this in terms of pounds, which means, parting from:
5 gallons = 37 pounds
Divide both sides by 37:
5/37 gallons = 1 pound
0.081 gallons = 1 pound
Every extra pound means 0.081 more gallons.
Now, as we want the weight of 3 gallons we can use our first relation and multiplying by 3:
1 gallon = 7.4 pounds
3 gallons = 22.2 pounds
