Answer:
= and and
Step-by-step explanation:
Absolute value -9 is 9, but there is a negative sign so it is -9
-9=-9
Greater than or equal to works because of the equal sign.
Less than or equal to also works because of the equal sign.
The width of the walkaway be 4 feet.
<h3>What is Discriminant Formula?</h3>
The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation is D =
If D > 0, then the equation has two real distinct roots.
If D = 0, then the equation has only one real root.
Given that:
also, area of walkaway = 464 square feet.
So,
Using Discriminant method,
a=4, b=100, c=-464
w=
w=
So,
Hence the width of the walkaway be 4 feet.
