If the endpoints of DE where D(-3, y) and E(x, 6) with the midpoint M(4, 2), the length of DE is 16.12 units
The formula for calculating the midpoint is expressed as;

For the x-coordinate points:
X = -3+x/2
4 * 2 = -3 + x
8 = -3 + x
x = 8 + 3
x = 11
Get the value of y;
2 = y+6/2
y+6 = 2 * 2
y + 6 = 4
y = 4 - 6
y = -2
Hence the coordinates of D and E are D(-3, -2) and E(11, 6)

Hence the length of DE is 16.12 units

Step-by-step explanation:
There are 4 possible ways he could have written it: chalk, pen, pencil, and marker.
There are 2 ways he wrote it: French and English
4*2=8
He wrote his name in 8 different ways.
195 miles
45x4=180
45 divided by 3=15
180+15=195
Answer:
(A)the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius
Step-by-step explanation:
Kareem plans to use the function
to convert temperature from degrees Fahrenheit to degrees Celsius.
The function gives a result in degrees Celsius. Therefore, 76.1 is in degree Fahrenheit and the result C(76.1) will be in degree Celsius.
Therefore, C(76.1) represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
The correct option is A.
Answer:

Step-by-step explanation:
Let the side length of the square base =s feet
Let the height of the box = h
Given that the volume of the box = 
Volume of the box =
Then:

Surface Area of a Rectangular Prism =2(lb+bh+lh)
Since we have a square base, l=b=s feet
Therefore:
Surface Area of our closed box
