The side length is 3 inches
<h3>What is the perimeter of a cube?</h3>
The formula for perimeter of a cube is given as:
Perimeter = 12 × side length
We have that;
- Perimeter = 36 inches
- Side length be x
Substitute into the formula
12x = 36
Divide both sides by 12
12x/12 = 36 / 12
x = 3 inches
The side length is x and equal to 3 inches.
Hence, the side length is 3 inches

Answer:
<h2>only x = 39</h2>
Step-by-step explanation:
x + 6 = 45 <em>subtract 6 from both sides</em>
x + 6 - 6 = 45 - 6
x = 39
A right triangle's longest side is the hypotenuse
let x=longest, y=middle, and z=shortest
x=y+2
y=2z-1
therefore x=(2z-1)+2=2z+1
find z
z^2+y^2=x^2 by Pythagorean theorem
plug in x and y in terms of z
z^2+(2z-1)^2=(2z+1)^2
z^2+4z^2-4z+1=4z^2+4z+1
subtract the right-hand side's value from the left-hand side's
z^2-8z=0
z(z-8)=0
z=0, 8
z cannot be zero as the sides must have some value to it.
Therefore the shortest side is equal to 8
Because 3 is a number and the x is unknow so its just an exponent the x ^ 3 grows three each time
