Answer:
The equation that represent x, the height of the sign is;

Step-by-step explanation:
Given that the area of the triangular yield is A square feet
and it has a base length of 3 feet.
also the height is represented by x;

Recall that the area of a triangle can be written as;

substituting the given;

Therefore, the equation that represent x, the height of the sign is;

Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0
