2,4


8+1=9
2+4=6


numbers are 2 and 4

if you were to solve it the
xy=8
x+y=6

y=6-x
x(6-x)=8
6x-x^2=0
0=x^2-6x+8
facotr
0=(x-2)(x-4)
set each to zero
x-2=0
x=2

x=4

x=2 or 4 and since they are interchangable, the numbes are 2 and 4

BRAINLIEST if right!
FromTheMoon [43]
Alright, so we know that 1 inch is 16 feet on the model. The model that we have is 11.5 inches in length.

To figure this out, simply multiply 11.5 by 16, which equals 184.

This gives us a ratio of 11.5 : 184, which is the same as 1 : 16. You can also write proportions as fractions, so 11.5 / 184 and 1/16 are the same, both equaling 0.0625.

The final answer is 184 ft
