Answer:
-40
Step-by-step explanation:
Try rearranging and factoring -8y-2c-2b-8x-2a:
This is equal to -8(x + y) -2(a + b + c).
Since x + y = 7, we have:
-8(7) -2(a + b + c)
and since a + b + c = 8, we end up with:
-56 - 2(8), or
-56 - 16 = -40
Answer:
1/6
Step-by-step explanation:
P(8) = number of 8's / total = 1/3
Then keeping the card so we have 7 and 9
P(7) = number of 7's / total = 1/2
P(8, keep, 7) = 1/3 * 1/2 = 1/6

Answer:
Step-by-step explanation:
Sum of exterior angles of regular polygons is 360°.
If each angle measures 15°, then the number of sides:
- 15n = 360
- n = 360/15
- n = 24
Area = length * width
241.2 = 15 * width
Width = 241.2/15 = 16.08 meters
Perimeter = 2*length + 2*width = 62.16 meters
