The length of a rectangle is 1 more yd than twice the width, and the area of the rectangle is 66 yd squared. Find the dimensions

Salsk061 [2.6K]

Width = 5.5yd

Length = 12yd

<u>Explanation:</u>

Area of rectangle = $66yd^{2}$

Let width of the rectangle = b ,

So, length = 2b+1

Area of rectangle = (length X width) - eqn 1

Putting the value of length and width in above equation 1,

$66yd^{2} = (2b+1) X b\\66yd^{2} = 2b^{2} + b\\2b^{2} +b-66 = 0\\$

On solving the equation we get,

b = 5.5yd

So, width (b) = 5.5yd

and length = 2(5.5) + 1

l = 12yd

Hence,

Width = 5.5yd

Length = 12yd

Answer:

$17.14

Step-by-step explanation:

Given : $y = - 0.34x^2 + 4.43x + 3.46$

To Find : Using the quadratic regression equation, what was the predicted profit in year 8

Solution :

$y = - 0.34x^2 + 4.43x + 3.46$

Where y is profit and x is year

Substitute x = 8

$y = -0.34(8)^2 + 4.43(8) + 3.46$

$y =17.14$

So, Option D is true

Hence the predicted profit in year 8 is $17.14
