What are two numbers that multiply to the value on top and add to the value on bottom

is this correct?

a * b = -70

a + b = -9a = -9 - b

b(-9 - b) = -70

-b^2 - 9b + 70 = 0

(-b + 5)(b + 14) = 0

-b + 5 = 0

5 = b

b + 14 = 0

b = -14

ur numbers are -14 and 5

-14 * 5 = -70

-14 + 5 = -9

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
