Make denomenators the same
times left denomenator by (x+3)/(x+3) and right one by (x-9)/(x-9)

if expandded we get
the sum of the squares of the lengths of the legs of a right triangle equal the square of the length of the hypotenuse
Explanation
Pythagorean theorem is related to the right angle triangle and it states that
c^2= a^2 + b^2
Where C is the length of the hypotenuse
a and b are the length of the sides of the triangle
The theorem states that the sum of the squares of the lengths of the sides of a right triangle is equal to the square of the length of the hypotenuse
Surface Area=2400
Step-by-step explanation:
To find the surface area we need to use this formula: Surface Area=6a^2
Where a is the side lengths that are being provided by the cube, now we plug in 20 as a into the formula.
Surface Area=6(20)^2
Surface Area=6(400)
Surface Area=2,400
Hope I helped, have a nice day :)
