7.5 is the answer have a good day
Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.
factors of 20 are 1,2,4,5,10,20
factors of 1 are 1
so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros
These are the steps needed for this question hope this helps if there is any more questions do feel free to ask them
To find the surface area you will find the area of each flat surface or each face.
The faces are in the shape of a rectangle , so multiply the length by the width.
A = lw
Front/ Back-3 1/2 x 3 1/3 = 11 2/3 ft.²
Sides- 3 1/3 x 3 1/3 = 11 1/9 ft.²
Top/bottom - 3 1/2 x 3 1/3= 11 2/3 ft.²
Add together to get the total surface area.
11 1/9+11 1/9+11 2/3+11 2/3+11 2/3+11 2/3 = 68 8/9 ft.²
The total surface area is 68 8/9 ft.².
2π is the period of `y = 1+ tan((1)/(2)x)`
