Question

The value of (0.525 x 0.525 - 0.275 x 0.275)/(0.525 - 0.275) is:

Answer 1

Answer:

It's quite simple : 0.8

Step-by-step explanation:

Let a = 0.525

b = 0.275

now, the given expression = (a^2 - b^2)/(a-b)

= (a+b)(a-b)/(a-b)

= a+b

= 0.525 + 0.275

= 0.8

Answer 2

Answer:

It's quite simple : 0.8

Step-by-step explanation:

Let a = 0.525

b = 0.275

now, the given expression = (a^2 - b^2)/(a-b)

= (a+b)(a-b)/(a-b)  

= a+b

= 0.525 + 0.275

= 0.8
