Answer:
C
Step-by-step explanation:
We need to find the area of BOTH the rectangle AND the triangle. So the formula to find area of a triangle is bh, or bh/2
b- base
h height
And obviously to find area of rectangles and stuff like that is just l x w
So let's find area of the rectangle, AKA the whole,
5x11=55
The area of the rectangle is 55
Now for the triangle,
The base is 5, and the height is 3. 5 x 3 = 15, and 15/2 = 7.5
The area of the triangle is 7.5
Now, subtract because we don't want the area of the triangle BUT the shaded region, so 55-7.5= 47.5 We have to add a unit so its 47.5^2, so the answer is C
Hope this helps!!

Answer as a compound inequality:
Answer in interval notation: [-4, 2)
=============================================
Explanation:
The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.
The lowest point occurs when y = -4. We include this value. So far we have which is the same as
The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that
Combine and
to get the compound inequality
This says y is between -4 and 2, including -4 but excluding 2.
To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.
