2(5x + 2)^2 = 48
divide both sides by 2
(5x + 2)^2 = 24
square root both sides to clear the power of two.
5x + 2 = + - sqrt24
subtract 2 from both sides
5x = -2 + - sqrt 24
divide both sides by 5
x = (-2 +-sqrt24)/5 or decimal answers .58 and -1.38

Answer:
<h3>246.6 meters per hour</h3>
Step-by-step explanation:
Step one:
Speed uphill 100meters per hour
Speed on flat ground 120 meters per hour
Speed uphill 150 meters per hour.
Required
The average speed.
Step two:
To get the average speed, let us add all the individual speeds and divide by 3(three different speeds), then multiply the result by 2(the return trip)
Average speed= (100+120+150)*2/3
Average speed= 740/3
Average speed= 246.6 meters per hour
