Answer:
.
Step-by-step explanation:
(5x^2 + 2y^2) * (3x^2 - 7y^2)
= 15x^4 + 6x^2y^2 - 35x^2y^2 - 14y^4
= 15x^4 - 29x^2y^2 - 14y^4
=

Answer: 114.37 ft
Step-by-step explanation:
If we model this situation as a right triangle, where the hypotenuse is the length of the ladder (), the opposite leg is the height the ladder will reach
, and the adjacent leg is the distance between the base of the ladder and the building (
); we have two options:
1) Using trigonometric functions, since we are given the angle
2) Using the Pithagorean Theorem
Any of the options will give a similiar result. So, let's choose the Pithagorean Theorem:
Isolating :
Adding to this height the extra height of (since the base of the ladder is at this distance above the ground, perhaps held by a firefighter truck):
This is the height the ladder will reach
