Answer:

{ \tt{(5r - 4)( {r}^{2} - 6r + 4) }} \\  = {  \tt{( {5r}^{3}  -  {30r}^{2}  + 20r - 4 {r}^{2} + 24r - 16) }} \\  = { \tt{ {5r}^{3} - 34 {r}^{2}  + 44r - 16 }}

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

What is an expression for the area of the shaded region? Simplify your answer.
Reptile [31]

Answer:

if it is put into a equation this would be it

2(x^2+6x+9) - (1.57)(x^2+6x+9)

Step-by-step explanation:

(x+3)(2x+6) - 1/2(3.14)(x+3)(x+3)

(2x^2+6x+6x+18) - 1/2(3.14)(x^2+3x+3x+9)

(2x^2+12x+18) - 1/2(3.14)(x^2+6x+9)

2(x^2+6x+9) - (1.57)(x^2+6x+9)

2(x^2+6x+9) is the rectangle at the bottom

(1.57)(x^2+6x+9) is the semicircle that is taking out of the shaded area
