Answer:
19.15
Step-by-step explanation:
so find the circumference of the circle using c=2*pi*r it's like 18.849. then find the perimeter of the box so p=2l+2w and it's like 38. so subtract the circle circumference from 38 so 38-18.849=19.15
Divide both by the least common denominator which is 4
The answer is 2/3
For this problem your answer is most likely C
The solution of the quadratic equation x² - 2 · x = - 26 is x = 2 ± i √ 22.
<h3>How to solve a quadratic equation by completing the square</h3>
Completing the square is an algebra-based method used both to simplify and to solve analytically quadratic equations. In this problem we proceed to complete the square to solve the equation, whose procedure is shown in detail:
x² - 2 · x = - 26 Given
x² - 2 · x + 4 = - 22 Compatibility with addition / Definition of subtraction
(x - 2)² = - 22 a² + 2 · a · b + b² = (a + b)²
x - 2 = ± √(- 22) Definition of square root
x - 2 = ± i √ 22 Definition of complex number
x = 2 ± i √ 22 Compatibility with addition / Existence of the additive inverse / Modulative property / Result
The solution of the quadratic equation x² - 2 · x = - 26 is x = 2 ± i √ 22.

1/3s+14=26
minus 14 both sides
1/3s=12
multiply both sides by 3/1
s=36
