Answer:
Width = 3 feet
Length = 7 feet
Step-by-step explanation:
x represents the width of doghouse so,
Width = x
Length is 4 times more than its width
Length = x+4
Area of doghouse = 21 square feet
We know
Area of rectangle = Length * Width
21 = (x+4)*x
21 = x^2+4x
=> x^2+4x-21=0
Solving the above quadratic equation by factorization to find the value of x
x^2+7x-3x-21=0
x(x+7)-3(x+7)=0
(x+7)(x-3)=0
x+7 =0 and x-3=0
x= -7 and x =3
Since the width of rectangle can never be negative so, x=3
Width =x = 3 feet
Length = x+4 = 3+4 = 7 feet
Answer:
2117 more fans
Step-by-step explanation:
So, all you do is just subtract 15,876 from 13,759, which gives 2117 more fans.
Hope I helped !!!
It is true. That is usually proved in every geometry course. It is one of the fundamental theorems of elementary geometry.
Question asks for answer in units of cubic feet so all dimensions must be converted from yards to feet.
ft x ft x ft = ft^3
Look up conversion: 1 yard = 3 ft
height = 2 yd * 3 = 6 ft
width = 9 ft
length = 3 yd * 3 = 9 ft
volume = 6 ft x 9 ft x 9 ft = 486 ft^3
Arranging the given data in ascending order:
1, 2, 2, 3, 3, 4, 7, 7, 7, 9
Meadian is the middle-most observation.
i.e. The Median here is average of 3 and 4.
= (3+4)/2
= 7/2
=3.5
Hope it helps...
