Earth: radius = 6378 kilometer, diameter = 12756 kilometers.
Answer:
13
Step-by-step explanation:
g(4) will be found by putting 4 in for r.
g(4) = 25 - 3(4)
g(4)= 25 - 12
g(4) = 13
Yes, you multiply the numerator by the numerator and the denominator by the denominator
Answer:
Step-by-step explanation:
(Assuming the den is a rectangle)
Let 
be the length of the den. Because the length is 10 feet longer than the width, the width of the den can be represented as 
.
The area of a rectangle is given as 
, therefore we can form the following equation:
Expanding this, we have:
This factors into 
, therefore 
.
Because -11 is extraneous, the length of the den is 
feet and the width is 
. Thus, the dimensions of the den are 
.
We first introduce midpoint formula
X1+X2 over 2;Y1+Y2 over 2
5+8 over 2 ; 6+2 over 2
x=13 over 2 ; Y=4
therefore midpoint=(13/4;4)
