Answer:
see below
Step-by-step explanation:
The greatest value for x
1x = 9
Divide by 1
x = 9
The least value for x
9x = 1
Divide by 9
x = 1/9
The scale is likely to show the mass is either 270.9g or 245.1g
Step-by-step explanation:
Actual mass = 258g
Percent error = 5% = ±0.05
Mass shown by scale = Actual mass*percent error

Therefore,
Mass shown by scale = 258+12.9 , Mass shown by scale = 258-12.9
Mass shown by scale = 270.9g , Mass shown by scale = 245.1g
The scale is likely to show the mass is either 270.9g or 245.1g

For example x^2=25
Without x the expression wouldn't exist, it allows you to calculate unknowns for example in a physics experiment using v=u+at
7x((185-36/3)-
(28/4)x (28/4)-(7x2)
7x173-(49-14)
=1211-63
=1148
