Help please

Answer 1

Answer:

1/2 (150 -2x)

Step-by-step explanation:

You know queen parallela has 150 meters to build her pen. That means that the perimeter of the pen must be 150 (meters), therefore if x is the width and L is the lenght, we have

2*x + 2*L = 150

We want the value of L in terms of x, so we will send 2*x to the other side of the equation and we have

2*L = 150 - 2*x

Therefore

L = (150-2*x)*1/2

The correct answer is 1/2 (150 -2x)

I hope this helped you!
