Larry is setting up a display of a 30 foot pioneer on the roof of the anderson building at boswell to celebrate a
great football season. to secure the pioneer, larry will tie a 34 foot rope to the top of the pioneer's head and
anchor it on the roof. how far from the base of the pioneer's feet will larry need to anchor the rope?

Larry will need to anchor the rope 16 feet away from the base of the pioneer's feet.

Step-by-step explanation:

We can use the Pythagorean theorem to solve this answer. The theorem states that . C represents the hypotenuse (the longest side of the triangle) and A and B represent the other two sides. We already know what C is (34, from the 34 foot rope) and we know one of the sides (30, from the 30 foot pioneer). Let's have side A equal 30. Now, all we need to do is solve for the final side:

We know now that the anchor will have to be 16 feet away from the pioneer's feet.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
