Answer:
<h2>C. 6x² + 6x² + 3x + 4</h2>
Step-by-step explanation:
The perimeter is the total of adding all of the side lengths together.
A square has 4 equal side lengths.
So the perimeter of a square is:
P = s + s + s + s or P = 4s
[P = perimeter s = side lengths of the square]
Since you know the side length of the square is (x + 2 1/4), you can replace s with (x + 2 1/4)
P = 4s
P = 4(x + 2 1/4) Multiply 4 into (x + 2 1/4)
P = 4x + 8 4/4
P = 4x + 9
Since you know the perimeter, you can plug it in.(you could have also plugged it in in the beginning)
P = 4x + 9
14 = 4x + 9 Subtract 9 on both sides
5 = 4x Divide 4 on both sides
5/4 = x
Now that you know x, find the side length of the square.
(x + 2 1/4)
(5/4 + 2 1/4)
2 6/4 = 3 2/4 = 3 1/2 units or 3.5 units
To find the area of a square, you multiply 2 of the sides together:
A = s · s
A = 3.5 · 3.5
A = 12.25 units²
Option C: 
is the slope of the line
Explanation:
The line passes through the points 
and 
We need to find the slope of the line.
The slope can be determined using the formula,
Where the coordinates 
and 
are and
Let us substitute the points in the formula
Thus, we have,
Simplifying, we get,
Adding the numerator and denominator, we have,
Cancelling the negative terms, we get,
Thus, the slope of the line is
Therefore, Option C is the correct answer.
Given:
The function is:
To find:
The result of the operation 
.
Solution:
If 
, then the graph of f(x) is reflected across the x-axis to get the graph of g(x).
We have,
The given operation is:
So, it will result in a reflection across the x-axis.
Therefore, the correct option is A.
Answer: y=-2
