Answer:
B. ≅
Step-by-step explanation:
Remember, for 
the x value of the vertex is 
so
given
x value of vertex is -5
and
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1
comlete the square
remember if we do
(h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand
a=-1
c=-5
so

Answer:
h =
Step-by-step explanation:
Given
A = (a + c)h
Multiply both sides by 2 to clear the fraction
2A = (a + c)h ( divide both sides by (a + c) )
= h
