A rectangle is four times longer than it is wide. It has an area of 16 square meters. What are the dimensions of the rectangle?

The width = 2 and the length = 8

Step-by-step explanation:

Let the width be x

The the length will be 4x

Area = 16

Area = l × w

16 = 4x × x

16 = 4x²

Divide both sides by 4

16/4 = x²

x² = 4

x = √4

x = 2

Therefore the width = 2 and the length = 8

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the answer is d on edge
