For Cecil's new act, his tightrope is 5 feet long. If he begins at point A, write two expressions that will make him end at point B. What do these expressions have in common? Explain why 5+2+(−2) is equivalent to (the same as) telling Cecil to move 5 feet to the right. Will 5+2+(−2)+2+(−2) get Cecil to point B? Will 5+2+(−2)+3+(−3)? How would you describe his movements in these cases?

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

step-by-step explanation:

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
