Answer:
x = 9
Step-by-step explanation:
-2x = 18 - 4x
-2x + 4x = 18
2x = 18
x = 18/2
x = 9
To solve for x, in the given equation;

we need to divide both sides of the equation by 2;

2x divided by 2 is equal to x, while 22 divided by 2 is 11.
So;
Answer:
x = 25
The lengths form a pythagorean triple
=========================================================
Explanation:
Use the pythagorean theorem to get the following

Since we end up with a whole number, we do form a pythagorean triple of 15,20,25 or you can write it as 15-20-25
A pythagorean triple is where a,b,c are all integers that satisfy the pythagorean theorem above.
This is not a primitive pythagorean triple because we could divide all three values by the GCF 3 to get the triple 3-4-5. The keyword for this paragraph is "primitive".
