So, the answer to 27.) would be <em>2x.</em> Both 6x and 2x can be divided by 2x, but they can't go any higher without the end-answer becoming a fraction. As such, 2x is the greatest common factor.
For 28.), x and x^2 can't be like terms, since like terms have the same variable and exponent :)
Hope I could help!
The second one, vocab and definition doesn't add up

Answer:1.4
Explanation:
Angle of incidence= 38°
Angle of refraction=26.3°
From Snell's law: n= sin i/sinr
sin i= 0.6157
sin r= 0.4430
n= 0.6157/0.4430=1.4
Note, n is dimensionless
