Since both x values are the same and since the y values are 18 digits apart, the distance between both points is 18 units.
Answer:
D) 
Step-by-step explanation:
The first step is to find the vertex.
Start with getting your coefficients:
a = 1, b = -6, c = 6
plug them into the equation 


Plug that back into the original equation to get y = -3
The vertex is going to be (3, -3)
The equation for Vertex Form is given by 
(a) being the coefficient in front of the 
(h) being the first point on the vertex (h,k) ({3},-3)
(k) being the second point on the vertex (h,k) (3,{-3})

Answer:
4 yd².
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 2⅔ yards
Width (W) = 1½ yards
Area (A) =.?
The area of the piece of fabric that Roberto needs can be obtained by using the formula for calculating the area of a rectangle. This is illustrated below:
Area (A) = Length (L) × Width (W)
A = 2⅔ × 1½
A = 8/3 × 3/2
A = 8 × ½
A = 4 yd²
Thus, the area of the piece of fabric that Roberto needs is 4 yd²
The answer is 4/14109 or 0.00028350 as a decimal
