If the legs of a right triangle are 3 and 6, what is the length of the hypotenuse? round your answer to the nearest thousands if needed be

6.708

You can find this using the a^2 + b^2 = c^2 method, substituting the length of the legs for a and b, while solving for c.

6.708.

The Pythagorean theorem for finding the hypotenuse of a right triangle is a^2 + b^2 = c^2. So the equation goes as follows.

a^2 + b^2 = c^2

(3)^2 + (6)^2 = c^2

9 + 36 = c^2

45 = c^2

C = 6.708

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
