4.Write a simplified polynomial expression to represent the area of the rectangle below. |dw:1323119912576:dw|4.

2. Mimi_x3

Just expand it. 1. 8x^6 + 6x^5 + 2x^4

3. bob06

1. 2x^4(4x^2 + 3x + 1) distribute the 2x^4: 8x^6 + 6x^5 + 2x^4 side note: what level of math are you in?

different answers ? ? i'm going with bob06 & mitosuki :)

6. bob06

no, we got the same answer

7. Mimi_x3

8. bridgettegale95

urs was just more explained and i'm turning that answer in...

9. bob06

for number 4, I can't totally see all the numbers, but basically u will need to take (side one) times (side two)

5.Write a simplified polynomial expression to represent the area of the square tile, shown below. |dw:1323120350190:dw|

11. bob06

which square tile? the outer one?

12. mitosuki

1. 2x^4(4x^2 + 3x + 1) 8x ^6 + 6x^5 + 2x^4 2. (4x – 3)(2x^2 – 7x + 1) 8x^3 - 28x^2 + 4x - 6x^2 + 21x - 3 8x^3 - 34x^2 + 25x - 3 3. (x^2 + 4x – 3)(2x^2 + x + 6) 2x^4 + x^3 + 6x^2 + 8x^3 + 4x^2 + 24x - 6x^2 - 3x - 18 2x^4 + 9x^3 + 4x^2 + 21x - 18

13. bridgettegale95

#4 at the bottom is 2x - 4 and on the side its x+5

14. mitosuki

Ok I believe those are the answers :O

15. bob06

oh, so #4 would be: (2x-4)(x+5)

16. bob06

what are you looking for in #5 again?

17. mitosuki

4. (2x-4)(x+5) 2x^2 + 10x - 4x -20 2x^2 + 6x - 20

18. bob06

oo yea, foil: first: 2x^2 outer: 10x inner: -4x last: -20 2x^2 + 6x - 20
