Step-by-step explanation:

Given:

The expression is

To find:

The simplified form of the given expression by using the distributive property and combining like terms.

Solution:

We have,

Using the distributive property, we get

On combining like terms, we get

Therefore, the simplified form of the given expression is .

1：13x-14

2:-6x+21

3: 20x-18

4:5x+15

5:14n+36

6:-12n+17

7:8n+32

8:k-11

9:-7k+37

10:-13k+34

11:2k+7

12:x+52

13:-2x+21

14:3x+21

15:12y-11

16:-26u+25

17:-42u+42

18:13u-7

1. 13x - 14

2. 21 - 6x

3. 20x - 18

4. 15 + 5x

5. 14n + 36

6. 9 - 12n

7. 8n + 32

8. k - 11

9. -7k +37

10. 36 - 13k

11. 2k + 7

12. 52 + x

13. -2x -21

14. 21 + 3x

15. 12v - 2

1. - A.

2.

Find the roots:

,

then

- C.

3. - D.

4. - C.

5.

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.

- A.

10. - B.

11. , the length is 6x+15.

12. - C.

13. .

14. - B.

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

Thanks so much! =^-^= Really helped a lot.

4x+8

6x-8

a) 4(x + 2)=4x+8

b) 2(3x - 4) =6x-8

c) 4(3 - 6x) 2x + 18-2(2 – 3x)

It will provide an instant answer!
