Answer:
25 square feet
Step-by-step explanation:
Check the picture below, so the circle looks more or less like that one.
well, the center of it is simply the Midpoint of those two points, and its radius is simply half-the-distance between them.

The answer is true .
Becasue Point - slope form : y - y1 = m ( x - x1 )
( x1 , y1 ) is the point given ; m = slope is given .
Answer:
<em><u> YOUR ANSWER IS 3</u></em>
Step-by-step explanation:
reduce the expression, if possible, by cancelling the common factors
and you would get 3 :)
2x + 5 = 27
2x + 5 (-5) = 27 (-5)
2x = 22
2x/2 = 22/2
x = 11
hope this helps
