Y=12 because the triangles have proportional side lengths
Answer:
1.) ax^2 + bx+ c =0
2.) parabola
3.) X=-b2a
4.) maximum
5.) minimum
Step-by-step explanation: hope this helps

The multiple zero is x = -4.
The multiplicity is 2 because there are two values of x.
20%
This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.
Slope formula: y2-y1/x-x1
We can use the given points to solve.
3-(-3)/7-5
6/2
3
Best of Luck!
