Answer:
B
Step-by-step explanation:
2x3=6 and 6x4=24 so 6-24= -18
Answer:
67
Step-by-step explanation:
To find exterior angles you add non-adjacent interior angles.
For volume you would do 20 x 8.5 x 7.5 = 1275 ft^3
For surface are you would add up all the area of the faces
left and right face = 8.5 x 7.5 = 63.75 each
front and back = 20 x 8.5 = 170 each
top and bottom = 20 x 7.5 = 150 each
total = 767.5 ft^2
Answer:
x = -1
Step-by-step explanation:
The vertex is halfway between the focus and the directrix.
So here the directrix is a vertical line to the left of the vertex and passing through the point (2-3, 9) = (-1, 9)
It is x = -1.
