(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. RonL
Hello, Originally Posted by CaptainBlack (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. RonL 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 check out my math game site hoodamath.com
