Answer:
A. 12
Step-by-step explanation:
If A and D are congruent, then 
which becomes 
after adding which then solves down to 
.
Answer:
a=2,b=4. (3a+b)=3*2+4=10.
Answer:
(2, -10)
Step-by-step explanation:
so first i find the axis of symmetry using the equation x= -b/2a
in this problem
a=3
b= -12
c= 2
- (-12)/ 2(3) = 2
2 will be the x point for your vertex
you then plug in your x point into the original equation and solve for y
y = 3(2)^2 - 12(2) +2
y = -10
Vertex is then (2, -10)
Sin2x = 2 sinx cosx
so 12 sinx cosx = 6 sin2x Answer
