The unknown side is 9. Because 9 x 5= 45, 45 being the perimeter, that is 5 times the unknown side. And 45 is the sum of 9, 16, and 20.
Answer: 
<u>Step-by-step explanation:</u>
Parabola Skate Rental: 4.50x + 35
Arc Hawk Skate Rental: 5.25x + 25
If you want to know when their cost will be the same, set the equations equal to each other.
5.25x + 25 = 4.50x + 35
0.75x + 25 = 35 <em>subtracted 4.50x from both sides</em>
0.75x = 10 <em>subtracted 25 from both sides</em>
<em>divided both sides by 0.75</em>
x =
<em>simplified the fraction</em>
Alright, lets get started.
The foreign exchange rate between the japanese yen and the euro is 190:1 given.
It means 1 euro = 190 yen

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient
----------> the value of A is 
Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares


therefore
the answer is
the value of A is
