Answer: 16 + 55 = 71cm^2
Step-by-step explanation:
You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.
First One:
It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4
4 x 4 = 16cm^2
The square footage without the door and the window is 246
Using the table, we will see that the function is:
t(l) = 3*l
<h3>
How to write the function?</h3>
Here we only have a table to work with, so we need to use that.
In the table, we can see the pairs:
- t(1) = 3
- t(2) = 6
- t(3) = 9
- t(4) = 12
So, in each new level, we just add 3 more toothpicks. Even more, we can see that the number of toothpicks is 3 times the value of l (the level) for all the cases in the table. So this is a linear function.
From that we can conclude that the function will be:
t(l) = 3*l

Answer:
f(2) = 5
Step-by-step explanation:
<h3><u>
Definitions:</u></h3>
Input values = x-coordinates.
- The input values are also known as the <u>domain</u>, which is the set of all real numbers. With the domain of a function, you could substitute any real number into a given function for x and produce a valid output.
Output values = y-coordinates
- The <u>range</u> is the set of all real numbers that depend on the input values plugged into the function. Thus, the range represents the output (y-values) that corresponds to the input values used into the function.
<h3><u>
Function Notation:</u></h3>
- In the function notation f(x), <em>f</em> is the function name, and <em>x</em> is your <u>input variable</u>.
- <u>Output values</u> are also called <u>functional values.</u> You could use any letter to represent a function name, such as g(x), w(x), etc.,.
<h3><u>Explanations:</u></h3>
This particular question asks for you to identify the corresponding output (y-value) of the given input value, x = 2. If you look at the graph, the x-coordinate, x = 2, corresponds to the y-coordinate of 5.
Therefore, f(2) = 5.
Attached is an edited screenshot of the graph that you posted, where it shows where f(2) = 5 is located on the graph.
