P = 2L + 2W
L = W + 6
P = 2(W + 6) + 2W
P = 2W + 12 + 2W
P = 4W + 12
5 + 2(3x + 4) + x
5 + 6x + 8 + x
5 + 8 + 6x + x
13 + 7x Stop Don't go any further. That's the 11th commandment: Thou shalt not combine unlike terms.
Paul has a long drive. If Shelly waits up she better have some snacks
4*65 + x = 500 The x stands for the number of miles left to go
270 + x = 500 Subtract 280 from both sides
x = 500 - 270
x = 230
Just so you know if he keeps going at 65 mph the amount time will be
230/65 = 3.53 hours.

Do 4x5, that is all you need to do, did you learn fractions in elementary?
For this, we will be using the quadratic formula, which is 
, with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: 
Firstly, solve the multiplications and the exponents: 
Next, do the addition: 
Next, your equation will be split into two: 
. Solve them separately, and your answer will be
