Write and simplify an expression to represent the perimeter of a rectangle whose length is twice the width.

Answers

Answer: 2x+4x

Step-by-step explanation:

Let's say x is the width, or the short side and 2x is the long side or length (since the long side is twice as long as the short side).

let's add those together.

x+2x

But with a perimeter, you have two short sides and two long sides. so let's multiply this expression by two.

2(x+2x)

multiply the two by each number.

2x+4x

The graph shows information about the lion population at a safari park.

Lions were introduced in the park in 2010. In 2012, the park has a population of 32 lions. A year later, in 2013, the park has 128 lions. Write an exponential function that models this situation. Let xrepresent the number of years since 2010 and let f(x)represent the number of lions.

Answers

Answer:

Where is the graph? I'm not sure how to answer your question without it...

Ok sooo if you get the exponents all together and then divide then you should get your answer but since you’re on here and you need it then I’ll give it to you : f(x)=4 ; sine the past (x)2years there has been f(x) 4 times as much as lions.
