Step-by-step explanation:
8 times 10 equals 80. 12 times 5 equals 60.
<h2>Ex 5</h2>
Simply multiply the equation by 6, in order to get rid of the denominators:
<h2>Ex 6</h2>
We have to rearrange the equation in the form
So that 
is the radius, and 
will be the diamater. We have to complete the squares: rewrite the equation as
You can see that 
is the beginning of 
Similarly, 
is the beginning of 
So, if we add 16 and 9 to both sides, the equation becomes
So, now we know that 
, and thus the radius is 13, so the diameter is 26.

Answer:
(5, 6 )
Step-by-step explanation:
Using the midpoint formula
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
with (x₁, y₁ ) = B(2, 1) and (x₂, y₂ ) = C(8, 11)
midpoint = [ 0.5(2 + 8), 0.5(1 + 11) ] = (5, 6 )
