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)
6 x 4=24 so the area of the donut 24 which is the answer to the question
The answer is p=2s+7. Two plants can be grown from each seed packet, and Erin already has seven plants so you add that to the equation as well.
-4 = x - 7
-4 + 7 = x
3 = x
Therefore x = 3
