**Add:**

**Question 1.**

**Solution:**

8ab + ( – 5ab) + (3ab) + ( – ab)

= 8ab – 5ab + 3ab – ab = 11 ab – 6ab

= 5ab Ans.

**Question 2.**

**Solution:**

7x + ( – 3x) + 5x + ( – x) + ( – 2x)

= 7x – 3x + 5x – x – 2x

= 12x – 6x = 6x Ans.

**Question 3.**

**Solution:**

**Question 4.**

**Solution:**

**Question 5.**

**Solution:**

**Question 6.**

**Solution:**

**Question 7.**

**Solution:**

**Question 8.**

**Solution:**

**Subtarct:**

**Question 9.**

**Solution:**

-5a²b – 3a²b = – 8a²b Ans.

**Question 10.**

**Solution:**

6pq – ( – 8pq) = 6pq + 8pq

**Question 11.**

**Solution:**

– 8abc – ( – 2abc)

= – 8abc + 2abc

= – 6abc Ans.

**Question 12.**

**Solution:**

– 11p – ( – 16p)

= – 11p + 16p

= 5p Ans.

**Question 13.**

**Solution:**

**Question 14.**

**Solution:**

**Question 15.**

**Solution:**

**Question 16.**

**Solution:**

**Question 17.**

**Solution:**

**Question 18.**

**Solution:**

**Question 19.**

**Solution:**

Let length of rectangle = 5x^{2} – 3y^{2}

and breadth = x^{2} + 2xy

Perimeter = 2(Length + Breadth)

= 2(5x^{2} – 3y^{2} + x^{2} + 2xy)

= 2(6x^{2} – 3y^{2} + 2xy)

= 12x^{2} – 6y^{2} + 4xy Ans.

**Question 20.**

**Solution:**

Perimeter of a triangle = 6p^{2} – 4p + 9

Sum of two sides of it = 3p^{2} – 5p + 3 + p^{2} – 2p + 1 = 4p^{2} – 7p – 4

Third side = (6p^{2} – 4p + 9) – (4p^{2} – 7p + 4)

= 6p^{2} – 4p + 9 – 4p^{2} + 7p – 4

= 2p^{2} + 3p + 5 Ans
