Multiply polynomials and simplify expressions (5/6x + 1/9) - (4/9 - x)

1.  - A.

2.  

Find the roots:

,

then

- C.

3.  - D.

4.  - C.

5.  

Find the roots:

,

then

and the width of the lawn is x-6 - A.

6. Since  the length and width are x+8 and x-3 - A.

7.  - B.

8. .

So the greatest common divisor is  - D.

9.  

Find the roots:

,

then

- A.

10.  - B.

11. , the length is 6x+15.

12.  - C.

13. .

14.  - B.

15. , the length of one side is 9p+5.
