X=the shortest leg
X+1= the longest leg
X+9=the hypotenuse.

Apply the Pythagorean theorem(a^2+b^2=c^2):
X^2 + (x+1)^2 = (x+9)^2

The sides=
20, 21, and 29

Answer:

Step-by-step explanation:

Since the numbers in the root is all the same, lets say $\sqrt{2}$ is a variable.

7x $\sqrt{2}$ - 4 $\sqrt{2}$ + x $\sqrt{2}$

Group with like terms:

7x $\sqrt{2}$ + x $\sqrt{2}$ - 4 $\sqrt{2}$

Combine like terms:

8x $\sqrt{2}$ - 4 $\sqrt{2}$

There you have it! Since all the square roots are the same thing, we can treat them like variables.
