Answer:
5 feet
Step-by-step explanation:
Total Area = Area of Triangle + Area of Square
60.5 = 35.5 + Area of Square (s²)
s² = 25
s = 5
36 total children
Ratio of boys to girls is: 3:1
36/4 = 9 9 children to each part of the ratio
9 x 3 = 27 total boys
9 x 1 = 9 total girls
The quadratic formula is shown below:
x = (-b±√(b^2-4ac))/2a
You have the equation 3x^2+5x+2 = 0; so "a", "b" and "c" are:
a = 3
b = 5
c = 2
When you substitute a=3, b=5 and c=2 in the Quadratic Formula, you get two roots:
x = (-5±√1)/6
x1 = (-5+1)/6 = -2/3
x2 = (-5-1)/6 = -1
The correct answer is "B":
x = -2/3, -1
