It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.
The area of a square is given by the equation
where s is the length of the side.

A=576
The area of this square is 576cm2.
Hope this helps!
Answer:
$2.50
Step-by-step explanation:
Answer:
Option C is correct ,14.2%
Step-by-step explanation:
In order to determine the effective tax rate of a taxpayer with taxable income of $52,000,the starting point to determine how much in taxes the taxpayer pays as shown below:
First tax bracket=$9,525*10%=$952.5
Second tax bracket=$952.50+(12%*($38700-$9,525))
=$952.50+$3501
Third tax bracket(where the taxpayer belongs)=4453.5
+(22%*($52,000-$38,700))
third tax bracket tax=4453.5+$2926
=$7379.5
Since the total tax payable of $7379.5 is now computed,
effective tax rate=tax paid/taxable income=7379.5/52000
=14.2%
The ordered pairs of the solution to the system of equation are [(3, 6), (-3, 18)]
<h3>System of equations</h3>
Given the following system of equations expressed as:
f(x) = x² - 2x + 3 and f(x) = -2x + 12
Since they are both function of x, hence;
x² - 2x + 3 = -2x + 12
x² - 2x + 3 + 2x - 12 = 0
x² - 9 = 0
x² = 9
x = ±√9
x = ±3
If x = 3
f(x) = -2(3) + 12
f(x) = 6
If x = -3
f(x) = -2(-3) + 12
f(x) =18
Hence the ordered pairs of the solution to the system of equation are [(3, 6), (-3, 18)]
