2x - 6y + 3x² + 7y - 14y = 3x² + (2x - 14x) + (-6y + 7y) = 3x² - 12x + y
Match of the equation with the verbal description of the surface would be :
Equation 1 = C. plane
Equation 2 = F. Circular cylinder
Equation 3 = C. plane
Equation 4 = E. sphere
Equation 5 = A. cone
Equation 6 = E. Sphere
Equation 7 = F. Circular cylinder
Equation 8 = B. Eliptic or circular paraboloid
Equation 9 = A. cone
Hope this helps
Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :

We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,

So, the distance between the two trees is 12.64 m.
26 units is the answers for this questions. To find the perimeter, put a slash in each square. The only squares that will get 2 slashes is the corners
