Answer:
see explanation
Step-by-step explanation:
If y is proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k divide both sides by x
k = 
This value must be constant for all ordered pairs, thus
k = 
= 
k = 
=
k = 
=
k =
Since k is constant for all ordered pairs then y is proportional to x

The slant height of a regular pyramid is 
Step-by-step explanation:
we know that
The lateral area of a regular pyramid is equal to
where
LA is the lateral area
P is the perimeter of the base
l is the slant height
we have
substitute in the formula and solve for l
