why not do it the hard way and waste precious time? a+b =11, a-b =8 a= 11-b , 8+b 11-b =8+b 2b=3 b=1.5, so a = 9.5 9.5^2 =90.25 -1.5^2 = 2.25 =88 Log in to Reply

why not do it the hard way and waste precious time?

a+b =11, a-b =8

a= 11-b , 8+b

11-b =8+b

2b=3

b=1.5, so a = 9.5

9.5^2 =90.25

-1.5^2 = 2.25

=88
