Step-by-step explanation: Since the width and length are consecutive odd integers, call the width <em>x</em> and the length <em>x + 2</em>.
Now, it would be helpful to draw a picture of your rectangle
and label its parts to help you set up the equation.
Since the perimeter of the rectangle is 120 meters,
<em>x + x + (x + 2) + (x + 2) = 120</em>.
Simplifying from here we get 4x + 4 = 120.
Now subtract 4 from both sides to get 4x = 116.
Now divide both sides by 4 to get x = 29.
So the width of our rectangle is 29 meters
and the length, <em>x + 2</em>, is 31 meters,
Answer:
The coordinates are A(-1,2)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
In this problem we have
substitute the given values
Solve for 
Solve for 
therefore
The coordinates are A(-1,2)
Answer: 4.5
Step-by-step explanation:
A half is 0.5 as a decimal. So:
4 + 0.5 = 4.5
