Answer:

5r³ - 34r² + 44r - 16

Step-by-step explanation:

\small \sf \: (5r − 4)(r² − 6r + 4)

use the distributive property

5r × (r² − 6r + 4) - 4× (r² − 6r + 4)

5r³ - 30r² + 20r - 4r² + 24r - 16

combine like terms

5r³ - 30r² - 4r² + 20r + 24r - 16

5r³ - 34r² + 44r - 16

Answer:    D: 17.3

Step-by-step explanation:

I believe its D because the house and the ground is a 90 degree angle, and at 60 degree angle is a 20 foot ladder. alright then 90 plus 60 = 150 degrees.

then add the twenty foot ladder with each choice for the answer:

A: 20 + 6.1 = 26.1

B: 20 + 10.0 = 30

C: 20 + 14.1 = 34.1

D: 20 + 17.3 = 37.3

The answer would be D because it is the closer number to 150. Because it says " which is the closest height up the house the ladder reaches?" The answer is D the closest number. I HOPE THIS HELPS YOU! =D
