<h2>Answer:</h2>

The equation which represents the situation is:

            x^2+6x-256=0

<h2>Step-by-step explanation:</h2>

Let x represent the width of the rectangle in centimeters.

The length of a rectangle is 6 cm more than its width.

This means that the length of the rectangle is: x+6 cm.

Also, we know that the area of a rectangle is the product of the length and width of the rectangle.

Here, the area of the rectangle is 256 cm².

i.e.

x(x+6)=256\\\\x^2+6x=256\\\\i.e.\\\\x^2+6x-256=0

jill traveled to the ferry office and back. the trip there took 5 hours and the trip back took 4 hours. she averaged 65 mph on t
antoniya [11.8K]

We know from physics class that the formula for distance of a linear motion is given as:

d = v t

Where,

d = distance travelled

v = average velocity

t = time it took to reach the destination

Since the distance going to the office and back is just similar, therefore we can simply equate the two:

v1 t1 = v2 t2

Where 1 signifies going to the office and 2 signifies going back from the office. Therefore this yields to:

v1 * 5 hours = 65 mph * 4 hours

v1 = 52 mph

 

<span>Answer: The average speed going to the office is 52 mph.</span>

A rectangle whose perimeter is 110 feet. The length is 4 times as long as the width. Find the length and the width.
madreJ [45]
Set up a system of equations.
l=4w
2l+2w=110

Substitute l in to the second equation.
2(4w)+2w=110
8w+2w=110
10w=110
w=11

Substitute w back into the first equation.
l=4(11)=44

So, the length is 44 feet and the width is 11 feet.

Hope this helped!
