85

Step-by-step explanation:

Use the  pythagorean theorem!

(think that is how you spell it )

Pythagorean theorem: a² + b² = c²

a and b are the numbers that you have in this example, c is the side you need!

75² + 40² = c²

5,625 + 1,600 = c²

7,225 = c²

(the square root and square cancel each other out)

85 = c

c = 85

b mark me branliest thx

step-by-step explanation:

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

you,
