I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132

Answer:
36 questions were correct.
Step-by-step explanation:
In order to find how many questions correct, you have to multiply it :
$25,000 - 5,000 = $20,000
Since the useful life is 10 years or 10% per year, double-declining rate would be 20%
Year 1
$20,000 x .2 = $4000
Book Value = $16,000
Year 2
$16,000 x .2 = $3,200
Book Value = ($16,000-3,200) =$12,800
Examining the table the functional notation is in the second option which is f ( x ) = x^2
<h3>How to determine the functional notations of the table</h3>
The table represents functions of input variables and the output variables.
The functional notation represents the relationship between the input and out variables
comparing the values and the function
f ( x ) = x^2
at x = -3 ⇒ f ( -3 ) = (-3)^2 = 9
at x = 0 ⇒ f ( 0 ) = (0)^2 = 0
at x = 1 ⇒ f ( 1 ) = (1)^2 = 1
This shows that f ( x ) = x^2 is the correct option
