(6.98X6.98-2.02x2.02)/4.96 ~= (7x7-2x2)/5=7
so the answer is approximatly 7, so 6.76 should be the correct answer if there is one in the list.

Sorry, but (7^2-2^2) /5=9.

I think 9 is the correct answer:
6.98^2-2.02^2=(6.98+2.02)(6.98-2.02).
Use the calculator if you are not sure.

Bye.

Hello, devi!

I got 9 as the answer . . . . Right!
but it was given that 6.76 is the answer . . . . They're wrong!

I have no idea where they got 6.76 !








The answer is: .

The answer has to be around 9

(7*7-2*2)/5
(49-4)/5
(45)/5
9
