1). If 2x-5 = x-9, then x = _______



2). If p = 3 and q = -2, then the value of 3pq-2q+5p is ________


3) The sum of the terms 13p, 6p and 2p is __________



4). If l = 20m and b = 15m, then the perimeter of the rectangle is ____


5). The perimeter of a square of side 50m is _______​

Answer 1

Step-by-step explanation:

1. x = -4
2. 1
3. 21p
4. perimeter of rectangle = 2(l+b)

= 2(20+15)

= 70 sq.m

5. perimeter of square =

side × side = 50 × 50 = 2500 sq.cm

Answer 2

Answer:

1. x = -4

2. 1

3. 21p

4.Perimeter of rectangle = 2(l+b) = 2(20+15) = 70 sq.m

5. Perimeter of square = side ×side = 50×50 =2500sq.cm
