Answer:
see explaination
Step-by-step explanation:
length (l) = 2x+7
width (b) = 9x
area of rectangle = l×b
=(2x+7)(9x)
=18x^2+63x
perimeter of rectangle = 2(l+b)
=2(2x+7)(9x)
=2(18x^2+63x)
=36x^2+126x
Find a number you can multiply by the bottom of the fraction to make it 10, 100, or 1000 and multiple both top and bottom by that number then write down just the top number putting the decimal point in the correct spot.
The total cost of 6 wave pool tickets with the discount included would be $73.5.
<h3>How to calculate the total value of 6 tickets with the discount?</h3>
To calculate the total cost we must multiply the value of each ticket by the number of tickets to be purchased, in this case there are 6:

Use algebra for such problems
let, Angle COD = x
Angle KOD = y
Angle KPC = z
Given ,. x - y = 61° ( Equation 1 )
x - z = 53° ( Equation 2 )
Subtract 1st equation from 2nd and you'll get :
z - y = 8° ( Equation 3 )
Now since , x + y + z = 180° ( Equation 4 )
Add Equation 3 to Equation 4 and you'll get
x + 2z = 188° ( Equation 5)
From Equation 2 we know that , x -z = 53°
or, x = 53° + z ( Equation 6 )
Put this value of 'x' in Equation 5 and solve for z. you'll get :
(53° + z) + 2z = 188°
or
3z = 188 - 53 = 135°
solving for z we get
z = 45°
put this value of z in Equation 5
x + ( 2 x 45° ) = 188°
or
x = 188° - 90° = 98°
hence , Angle COD = 98°
