X x Y = -48 and X + Y =9

So X = 9 - Y then (9 - Y) x Y = -48

then -YxY + 9 x Y = -48 or YxY - 9 Y - 48 = 0 (rewritten)

Then use discriminant, Delta = (-9)x(-9) - 4 x 1 x -48 = 273

So

Y = (9 - sqrt(273)) / 2 and X = 9 - Y = 9 - ((9 - sqrt(273)) / 2

OR

Y = (9 + sqrt(273)) / 2 and X = 9 - Y = 9 - ((9 + sqrt(273)) / 2

They are: 7 times 7 = 49

multiplied to seventy and add to nine is impossible, but add up to 9 and multiplied to -70, or add up to -9 and multiplied to 70 are possible. In that case, 14 and -5 would do it (or -14 and 5)

No two numbers that can be completely written down with digits can be added, subtracted, multiplied, or divided to equal PI. If they could be divided to equal PI, then PI would be a rational number. But it isn't.

They are: 7 times 7 = 49

I believe that the numbers One and Nine fit the bill as they would be 1x9= 9 and 1+9=10.

They are: 3*3 = 9

The square root of 9 is the number which, when multiplied by itself, equals nine. There are two numbers which, when squared, equal nine: positive three and negative three. Depending on the context of the question, one of the numbers may not make sense as an answer, or they both may work as answers.
