Answer:
length = 21 inches
Step-by-step explanation:
Missing information
In this question some information is missing the width is not given in the question .The width in this question is 4 inches we have to find the length of the rectangle .
We know that the perimeter of rectangle is given as
........................equation(1)
where p=perimeter
w= width
l= length
Now putting the value of width and perimeter in the equation(1) we get ,
50=8+2l
50-8=2l
42=2l
Therefore length of the dimension is 21 inches
Answer:
Option D
Step-by-step explanation:
Given
Required
Determine if the function is quadratic
Start by representing the function as an x-y table
x:- 5 || 7 || 9 || 11
y:- 7 || 11 || 14 || 18
Next; Calculate the difference between the values of y
<em>The resulting difference are: 4 || 3 || 4</em>
Next; Calculate the difference between the difference of values of y
<em>The resulting difference are: -1 || 1</em>
<em>For the function to be quadratic, the above difference must be the same and since they are not, then the function does not represent a quadratic function.</em>
<em>Option D answers the question</em>
Answer:
117 mi²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (b₁ + b₂), substitute values
= × 6 × (14 + 25)
= 3 × 39
= 117 mi²
