Help sorry nothing was attached last time

Given:

The area of a rectangle is 99 square yd.

Length of the rectangle = 7 yd more than twice the width.

To find:

The dimensions of the rectangle.

Solution:

Let x be the width of the rectangle. Then, length of the rectangle is:

Length=2x+7

Area of a rectangle is:

A=length\times width

A=(2x+7)\times x

A=2x^2+7x

The area of a rectangle is 99 square yd.

2x^2+7x=99

2x^2+7x-99=0

Splitting the middle term, we get

2x^2+18x-11x-99=0

2x(x+9)-11(x-9)=0

(x+9)(2x-11)=0

Using zero product property, we get

(x+9)=0 and (2x-11)=0

x=-9 and x=\dfrac{11}{2}

x=-9 and x=5.5

Width of the rectangle cannot be negative. So, x=5.5 yd.

Now, the length of the rectangle is:

Length=2x+7

Length=2(5.5)+7

Length=11+7

Length=18

Therefore, the length of the rectangle is 18 yd and the width of the rectangle is 5.5 yd.

Answer:

3.6 miles

Step-by-step explanation:

The three points form a right triangle. The hypotenuse is the distance from Bruce and Avery's house, and the first leg is the distance from Avery's house to the school. Using the Pythagorean Theorem's converse, sqrt(7^2-6^2), and rounding it to the nearest tenth, we get 3.6 miles.
