Question 14) 3³
question 15) 100/9
Answer:
The circle's circumference is equal to 14π yards.
General Formulas and Concepts:
<u>Geometry</u>
Circumference of a Circle Formula: C = πd
- <em>d</em> is the diameter of the circle
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
<em>d</em> = 14 yds
<u>Step 2: Find Circumference</u>
- Substitute in variables [Circumference Formula]: C = 14π yds

Answer:
The flower garden width would be 6 ft
Step-by-step explanation:
A = 12 ft^2 = x(x + 4) becomes:
x^2 + 4x - 12 = 0, or (by completing the square) x^2 + 4x + 4 - 4 - 12 = 0
Thus, we have (x + 2)^2 - 16 = 0, or (x + 2)^2 = 16
Taking the square root of both sides yields x + 2 = ±4.
In this context only a positive x value makes sense: x = 2 + 4 => x = 6.
The flower garden width would be 6 ft. The other dimension would be 6 - 4, or 2, ft.
(9)(3) would be the expression for the factors rounded to the nearest whole numbers.
I hope I correctly answered your question and that this helps.
