For this question, we use the Pythagorean theorem.
We know the lengths of the legs, a and b.
Now, let's solve for the hypotenuse, c.
Take the positive square root.
Hope this helps! :)
Answer:
x = 3
Step-by-step explanation:
First distribute
2x + 4x - 4 = 2 + 4x
combine like terms
6x - 4 = 2 + 4x
continue
2x - 4 = 2
add 4 to both sides
2x = 6
divide both sides by 2
x = 3
