Answer:

The new area is 12

Step-by-step explanation:

First, divide each number by 3

12 ÷ 3 = 4

9 ÷ 3 = 3

Then, multiply 4 × 3.

4 × 3 = 12

The new area is 12

The perimeter of a rectangle is 15x+17y. if the length is 7/2x+7y, then find the width of the rectangle
Alexxandr [17]

Answer:

A

Step-by-step explanation:

Length : \frac{7x}{2} + 7y

Perimeter: 15x + 17y

Perimeter = 2(Length + Width)

15x + 17y = 2( \frac{7x}{2} + 7y + Width)

15x + 17y = 7x + 14y + 2(Width)

15x + 17y -7x -14y = 2(Width)

8x + 3y = 2(Width)

Width = \frac{8x + 3y}{2}

Width = 4x + 3y/2

The rectangle below has an area of x^2-144 square meters and a length of x+12 meters. What expression represents the width of th
Elanso [62]
Since length*width=area, (x+12)*width=x²-144. Dividing (x+12) from both sides, we get (x²-144)/(x+12)=width. One formula we can use is that
(a²-b²)=(a-b)*(a+b). Since 144=12², that means that x²-144=(x-12)*(x+12). Plugging that in, we get (x-12)*(x+12)/(x+12)=(x-12)=width

A rectangle has an area of 900square inches. The length of the rectangle is 2.25 times the width.Find the dimensions
Alexeev081 [22]

Answer:

Length = 45 inches and Width = 20 inches

Step-by-step explanation:

Let the width be w.

Length(l)=2.25w

Area = 900 in^2

The formula for the area of a rectangle is Area = length * width

So substituting our values we get:

A=2.25w*w\\900=2.25w*w\\2.25w^2=900\\w^2=\frac{900}{2.25} \\w^2=400\\w=\sqrt{400} \\w=20

So we get width = 20 inches

Length = 2.25w

so Length= 2.25*20

=45 inches
