Question

The



a.m of two numbers is 40 and g.m is 32 .the numbers are

Answer 1

Best Answer: (x + y) / 2 = 40

sqrt(xy) = 24

x + y = 40 * 2

x + y = 80

y = 80 - x

xy = 24^2

xy = 576

x(80 - x) - 576 = 0

80x - x^2 - 576 = 0

x^2 - 80x + 576 = 0

x = (-(-80) +/- sqrt((-80)^2 - 4(1)(576))) / (2*1)

x = (80 +/- sqrt(6400 - 2304)) / 2

x = (80 +/- sqrt(4096)) / 2

x = (80 +/- 64) / 2

x = (144 or 16) / 2

x = 72 or 8
