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.
Answer:
ummmmm I guess I could add the dimensions in the text.
Step-by-step explanation:

The lengths of the sides of the triangle are 8, 8, 20
Explanation:
Given that the perimeter of an isosceles triangle is 36 inches.
The base of the triangle is
times longer than each of its legs.
We need to determine the lengths of the sides of the triangle.
<u>Lengths of the sides:</u>
Let x denote the lengths of the sides of the triangle.
The base of the triangle is given by
![2\frac{1}{2}x=\frac{5}{2}x=2.5x](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7Dx%3D%5Cfrac%7B5%7D%7B2%7Dx%3D2.5x)
Perimeter of the isosceles triangle = Sum of the three sides of the triangle.
Thus, we have,
![36=x+x+2.5x](https://tex.z-dn.net/?f=36%3Dx%2Bx%2B2.5x)
![36=4.5x](https://tex.z-dn.net/?f=36%3D4.5x)
![8=x](https://tex.z-dn.net/?f=8%3Dx)
Thus, the length of the sides of the isosceles triangle is 8 inches.
Base of the triangle = ![2.5(8)=20 \ inches](https://tex.z-dn.net/?f=2.5%288%29%3D20%20%5C%20inches)
Hence, the three sides of the isosceles triangle are 8, 8, 20
Answer: B
Step-by-step explanation:
9/6 divided by 3/2
you flip 3/2 to 2/3 and multiply
9/6 times 2/3 = 1
