The figure shows a square and 4 congruent isosceles triangles. If the length of leg x is 12 feet, what is the length in feet of the hypotenuse of each triangle?​

wher eis the

Step-by-step explanation:

hypotenuse = 13 feet

Step-by-step explanation:

base of triangle is 10 feet

x=12 feet

1/2 base =5 feet

use Pythagorean theorem

5^2+12^2=hypotenuse^2

25+144=169

sq root 169=13

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
