Me ! i am not the best at math

Pipe 1=5√96=5√(6*2⁴)=5*2²√6=20√6
pipe 2=12√150=12√(6*5²)=12*5√6=60√6
pipe 3=2√294=2√(6*7²)=2*7√6=14√6

piping=pipe 1 + pipe 2 + pipe3
piping=20√6 + 60√6 + 14√6=(20+60+14)√6=94√6

94√6  (this is the correct answer)

your choices are not corrects

The slope of the function is 0.5.
