X = 7
5 + x can also be written as 5 + 7
5 + 7 = 12
The answer is c. If the answer is wrong i am sorry
Rewrite the parabola in standard form and use this formula to find the vertex (h,k).
= (2,-1)
In (A), we have 9 : 2.
Multiply by 2, we get 18 : 4
In (B), we have 36 : 8.
Divide by 2, we get, 18 : 4.
In (D), we have 54 : 12.
Divide by 3, we get, 18 : 4.
Hence, (C) is not equivalent to the given statement.
