The rectangle shown has an area of (y^2+8y+15)m^2 what is the width of the rectangle

1 answer:

4 0

If the dimensions are "nice" factors of the quadratic, and if y > -3, we have
.. area = (y +3)(y +5)

y+5 is greater than y +3, so we take the width to be ....
.. width = y+3

Bogdan [553]

Answer:

6 hours

Step-by-step explanation:

Answer:

6 hours

Step-by-step explanation:

Firstly, it is important to know where the train that leaves Washington will get after one hour since they didn't start at the same time between noon and 1 is 1 hour.

Speed = distance / time

Distance = speed * time

The distance S = 44 * 1

S= 44m

To determine the time they will pass each other

500(total distance)- 44 ( distance gotten to in 1 hour) - d(the distance it willl pass each other =44* t(time the train will pass each other.

456-d =44t

Second train

d = 32t

Substituting to the equation

456-32t=44t

456=76t

t= 6 hours.

The time they will pass each other is six hours.
