Andre went hiking near his house. the first trail he hiked on took him 4.5 miles away from his house. the second trail he hiked took him 2.4 miles closer to his house. the thrid trail took him 1.7 miles further away from his house. after andre hiked the three trails, how far from his house was he?

He is 3.8 miles away from his house.

Explanation :

Distance the first trail took him away = (+) 4.5 miles

( We will show it with positive sign as it increase the distance away from the house)

Distance the second trail took him closer = (-) 2.4 miles

(We will show it with negative sign as it decreases the distance)

Distance the third trail took him far away = (+) 1.7 miles

Now , total distance = 4.5-2.4+1.7

                                  = 3.8 miles

∴  He is 3.8  miles far his house.

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
