Answer: The 2nd option is correct.
Step-by-step explanation:
Since you have started off with 4 players, the number line needs to start at 5, because 9 - 4 = 5. This gives us the answer of the second option, because it starts at 5 and goes to the positive side.
Convert to vertex form:-
y = 5(x^2 - 2x) + 1
y = 5[(x - 1)^2 - 1] + 1
y = 5(x - 1)^2 - 4
vertex is (1, -4)
Answer:
the surface area is 133cm.
7 x 7 is 49
7 x 6 is 42.
42 divided by 2 is 21.
21 x 4 is 84
So 84 + 49 is 133.
