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.

The coordinates for M is (4,5)
Answer:
Step-by-step explanation:
what
Answer:
m∠A = 115°; m∠C = 50°
Step-by-step explanation:
∠A + ∠B + ∠C = 180
4x – 13 + 15 + x + 18 = 180 Combine like terms
5x + 20 = 180 Subtract 20 from each side
5x = 160 Divide each side by 5
x = 32
∠A = 4 × 32 – 13
= 128 – 13
= 115°
∠ C = 32 + 18
= 50°
<em>Check:
</em>
115 + 15 + 50 = 180
180 = 180
Answer:
12.56cm.
Step-by-step explanation:
Given that the diameter of a circle is 4 centimeters
The equation to find the circumference would be C=πd
C=3.14x4
=12.56
The circumference of the circle would be 12.56cm.
Hope this helps :)
