Answer:
9 yd
Step-by-step explanation:
A cube consists of 6 square faces.
Divide the surface area by 6 for the area of one face
486 ÷ 6 = 81 yd²
The area of a square is
A = s² ( s is the side length )
Here A = 81, then
s² = 81 ( take the square root of both sides )
s =
= 9
Thus side length is 9 yd

Answer:
x=-11
Step-by-step explanation:
the (x+14) line is half of the (17+x) line, so in order to solve this we would have to set it up like this:
2(x+14)=17+x
distribute
2x+28=17+x
x=-11
