If mr. arenth wants to put new carpeting in the room shown, how many square feet should he order l= 14ft. w = 6c-8ft. l= 5+3c ft.

By definition, the area is given by:

Where,

w: width

l: length

We have two expressions for the length:

Since the length is the same, we equate both expressions:

From here, we clear the value of c:

Then, we have that the width is given by:

Substituting the value of c we have:

Finally, the area is given by:

he should order 140 square feet

-1/2 +2

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
