XY= -45
X+Y = 16
Y = 16-X
X(16-X) = -45
16X -X2 + 45 = 0
multiply both sides by -1
x2 -16X - 45 = 0
x =(16+/-sqrt(256+180))/2
x = 18.44 and -2.44
272 / 17 = 16
It is 152 times 45 = 6840
4x16=64 that is the final answer
Square root of 45 times square root of 45 = 45
They are: 3 times 15 = 45, 9 times 5 = 45 and 1 times 45 = 45
It is: 11.25*4 = 45
It is: 5 times 9 = 45
6.708203932499369 x 6.708203932499369 = 45
4.95555555555556 x 45 = 223
42 x 45 = 1,890
45 * 30 = 1350
