Answer:
The length of the sides is <u>7 In</u>.
Step-by-step explanation:
Given:
A cube has a surface area of 294 sq. In.
Now, to find the sides.
Let the side be 
Putting the formula of area to get the length of side:


<em>Dividing both sides by 6 we get:</em>

<em>Using square root on both sides we get:</em>

Side = 7 In.
Therefore, the length of the sides is <u>7 In</u>.
6x^2-5x-1>0
(6x-1)(x+1)
x=1/6 x=-1
The answer B represent the liner function
The angle does not matter. Think of it as finding the other side to a triangle. Use

a=39 (line AB)
b=b (the leg we need to find)
c=89 (line BD)


(subtract the 1521 from both sides)

(square root both sides)

b = 80
AD=80
