98-7x=3x+18. -7x-3x=-98+18. -10x=-70. X=7.
Can I see ur questions so I can help
The domain is the set of feasible inputs, i.e. the x-coordinates in which you can evaluate the function.
We can see that this function is defined only for x values between -1 and 3 (included), so this is your domain.
Well the simple answer would be 96 the surface of 96 cm
