13) 2x^2

14) Cost Price

15) (x^2)+xb+ax+ab

Answer 2

Answer:

1. cost of 12 pencils is ₹12.48

so, C. P of 1 pencil is ₹(12.48/12) =₹ 1.04

3. 2x^2

2. 4.5×10^4 = 4.5×10000= 45000

4. cost price

5.(x-a)(x-b) is equal to x^2-xb-ax-ab= x^2 -x(b+a) –ab or = x^2 -b(x+a) –ax. The x minus a and b takes the quadratic formula and includes steps that should govern with above formula by operating and come across in an identify of same sort.
