Answer:
i think its the first answerr
Step-by-step explanation:
3x(x+3)^2 is your answer
start 3x^3+18x^2+27x
Pull out common factor of 3x
3x(x^2+6x+9)
Factor into 2 (x+3)s
then <span>combine
</span>3x(x+3)^2
Your factors are 3x, (x+3) and (x+3)

Answer :y=4 x=2
Step-by-step explanation:
We let y equal to the elevation above sea level so that the elevation of the rock climber after x minutes of climbing would be:
y = 2x + 50
His initial height can be calculated when x is equal to zero it is when the climber is not yet climbing. Therefore, the rock climber'sinitial height above sea level would be 50 meters.
