do you have a picture with it??
Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)
Two sides would=2 which would have 2 sides had up to 4, and the other two sides would= 1 which would have those two added up to 2, 4+2=6
The exponential function with a growth factor has a rate greater than 1
The percentage growth rate is 276%
<h3>How to determine the percentage growth rate?</h3>
The growth factor (b) is given as:
b = 3.76
The growth factor (b) is greater than 1.
So, the percentage growth rate (r) is calculated as:
r = b - 1
Substitute known values
r = 3.76 - 1
Evaluate the difference
r = 2.76
Express as percentage
r = 276%
Hence, the percentage growth rate is 276%

A) 5/10 = (5/10)*(10/10) = 50/100
b) 47/100 +50/100 = (47+50)/100 = 97/100
