Answer:
12+27a
Step-by-step explanation:
3(4+9a)=3(4)+3(9a)=12+27a
27 x 26 x 28 x 34 x 45 = 30,073,680
Answer: 9
Step-by-step explanation:

Answer:
Option D.
Step-by-step explanation:
The vertex form of a parabola along y-axis is
...(1)
where, (h,k) is vertex and a is a constant.
From the given graph it is clear that the vertex of the parabola is (0,2). So, h=0 and k=2.
...(2)
The graph passing through (6,5). Substitute x=6 and y=5 in the above equation.
Substitute
in equation (2).
Therefore, the correct option is D.
