Find the area of the shaded region.

Step-by-step explanation:

First do 9 times 9 times 9

40.5 m2

Step-by-step explanation: first you have to calculate the area of the square.

Then, because the shaded area is half the square, you just divide the area of the square between two

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

is there a question here?
