20 x 10 = 200 
45 - 10 = 35 - 8 = 27 
8 x 8 = 64
20 - 8 = 22 
22 x 45 = 990
The area of the shape is 990 square feet. 

Hope I could help!

Break the shape into 3 different shapes and calculate the area of those shapes.

Shape 1: 10*8 = 80 ft^2
Shape 2: 27*12 = 324 ft^2
Shape 3: 8*8 = 64 ft^2

Then add those shapes up:

80+324+64 = 468 ft^2

Which function has a vertex on the y-axis? f(x) = (x – 2)2 f(x) = x(x 2) f(x) = (x – 2)(x 2) f(x) = (x 1)(x – 2)
makvit [3.9K]

The function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)

<h3>How to determine the function?</h3>

For a function to have its vertex on the y-axis, then the coordinate of the vertex must be:

(h,k) = (0,y)

A quadratic function is represented as:

f(x) = (x - h)^2 + k

So, we have:

f(x) = (x - 0)^2 + k

Evaluate

f(x) = x^2 + k

From the list of options, we have:

f(x) = (x - 2)(x + 2)

Expand

f(x) = x^2 - 4

Hence, the function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)
