Answer:
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Step-by-step explanation:
we know that
The area of the rectangle (movie screen) is equal to

where
L is the length
W is the width
we have

so
----> equation A
The screen is 20 feet longer than it is wide.
so
---> equation B
substitute equation B in equation A

solve for W

solve the quadratic equation by graphing
the solution is W=82 ft
see the attached figure
Find the value of L

therefore
The dimensions of the screen are
Length:102 feet
Width: 82 feet
5x^2= 2205
Divide both sides by 5
x^2=441
Find the square root of both sides
x= 21
Answer:
<u><em>3544.392</em></u>
Step-by-step explanation:
The value of the total number of population is P=2000The value of the rate of interest isR%=4.5%The value of the time is T=13yrs
For compounded annually
n=1
The expression for the final value of the population after
13years is,A=2000(1+4.5100)13=3544.392
if you can give me brainliest that would be great
