Find the area of the rectangle with the given base and height.
podryga [215]

Answer:

<u>The area of the rectangle is 5.5 feet² or 5 1/2 feet²</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Base of the rectangle = 11 feet

Height of the rectangle = 6 inches

2. What is the area of the rectangle in square feet?

Area of a rectangle = Base * height

For calculating the area in square feet, we need to convert the height from inches to feet.

12 inches = 1 feet ⇒ 6 inches = 0.5 feet

Therefore,

Area of the rectangle = 11 * 0.5

<u>Area of the rectangle = 5.5 feet² or 5 1/2 feet²</u>

Which of the following functions best describes this graph ?
IrinaVladis [17]

Answer:

<h2> y = x{}^{2} - 9x + 20</h2><h2 />

Step-by-step explanation:

As seen from the graph , the function cuts the x-axis at 4 and 5. So, the roots of function are 4 and 5.

The function becomes :

( x - 4 ) ( x - 5 )

Expanding:

(x - 4)(x - 5)

x(x - 5) - 4(x - 5)

{x}^{2}  - 5x - 4x + 20

{x}^{2}  - 9x + 20

So, after expansion , it becomes :

{x}^{2}  - 9x + 20

So, Option D is the correct option.

Hope this helps..

Best regards!!
