If we set the equation equal to 0, we can factor it to find its roots:
x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2
This graph has one root, a double root, at -2. This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)
Answer:
The answer is C. 10
Step-by-step explanation:
7.8333333 will be the answer
It is D. ,that one makes the most sense to me
5,000 × 3.8%= 19,000×18= 342,000 × 40 = 13,680,000
