Answer:
50.24 mm^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
A = 3.14 ( 4)^2
= 50.24 mm^2
(x*2 + 11x)+ 24
half of 11 is 5.5*2
(x*2+ 11x + 30.25 ) + 24 -30.25
(x*2 + 11x) -6.25
so
Vertex (11,-6.25)
The answer is 5 because 10 minus 5 is 5, so the difference is 5.
9m+5=-13
9m=-18
m=-18/9
m=-2
