The length and width of a rectangle are consecutive odd integers. The perimeter is 120 meters. Find the length and width

1 answer:

3 0

Step-by-step explanation: Since the width and length are consecutive odd integers, call the width x and the length x + 2.

Now, it would be helpful to draw a picture of your rectangle

and label its parts to help you set up the equation.

Since the perimeter of the rectangle is 120 meters,

x + x + (x + 2) + (x + 2) = 120.

Simplifying from here we get 4x + 4 = 120.

Now subtract 4 from both sides to get 4x = 116.

Now divide both sides by 4 to get x = 29.

So the width of our rectangle is 29 meters

and the length, x + 2, is 31 meters,

Suppose Johnny invests $41,745 into an account, which has been earning interest for many years and he now has a total of $39,974

Dmitriy789 [7]

Answer:

A negative number would be reasonable in the solution of the rate of the investment. It would be reasonable because Johnny started out with $41,745 in his account and ended up with $39,974 which means that the rate has to be negative.

Questions:

A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?

Answer:

32 units of fabrics

Step-by-step explanation:

Given

$a = \sqrt{f + 4} - \sqrt{36 - f}$
