By how much must 5p² - 3p² be diminished to give 2p² + q²? ​

3p² - 4q²

5p² - 3q² - (2p² + q²)

5p² - 3q² - 2p² - q²

3p² - 4q²

5p² - 3q² - (3p² - 4q²)

5p² - 3q² - 3p² + 4q²)

2p² + q²

answer:

xx

answer:

step-by-step explanation:

use pythagorean theorem to solve for the horizontal distance along the ground between the bottoms of ladder and building.  

the pythagorean theorem states that the square of the hypotenuse (c) of the right triangle (with a 90-degree angle) is equal to the the sum of the squares of its two other sides a and b.

to visualize the given problem:

therefore:

find   b, the distance from the bottom of the ladder to the bottom of the building:

c² = a² + b²

(26 ft)² = (10 ft)² + b²

b² = (26 ft)² - (10 ft)²

b² = 676 ft² - 100 ft²

b = √(576 ft²)
