What is the GCF of the polynomial given below?
60ax - 40ay + 50az

10a, all of the numbers can be divided by 10a

10a (6x − 4y + 5z) = 60ax - 40ay + 50az

The side x is the hypotenuse of the triangle.

And we know that the leg that is labeled with a line is also 6.

Use the Pythagorean theorem and solve for x.

a² + b² = x²
3² + 6² = x²
9 + 36 = x²
45 = x²
√45 = x
√9×5 = x
√9√5 = x
3√5 = x

The answer is 3√5

Hope this helps :)
