Answer:
(-2, -1).
Step-by-step explanation:
y = x² + 4x + 3
Completing the square:
y = (x + 4/2)^2 - (4/2)^2 + 3
y = (x + 2)^2 - 4 + 3
y = (x + 2)^2 - 1.
This is vertex form and the coordinates of the vertex are (-2, -1).
Just multiply the with and the length by four (considering the scale factor is 4)
3x4=12 and 7x4=28
Answer:
C≈94.25in d Diameter 30in Using the formulas C=2πr d=2r Solving forC C=πd=π·30≈94.24778in
