Answer:
Step-by-step explanation:
The given equation is
Factoring by x:
One of the root is x=0. Let's solve the parentheses.
Expanding the trinomial
Factoring
Factoring
This will give us the two remaining roots
The equation that says the area is 40, 000 yards squared is 40,000 = (5x + 300)x
<h3>How to find area of a rectangle?</h3>The area of a rectangle can be found as follows:
area of a rectangle = lw
where
Therefore, the equation that says the area of the yard is 40, 000 yards squared is as follows:
l = length = 5x + 300
w = width = x
Therefore,
area = (5x + 300)x
40,000 = (5x + 300)x
