Step-by-step explanation:
3×3=9. 3 faces so 9×3=27
10×3=30. 4 faces so 30×4=120
6×3=18. 2 faces so 18×2= 36
15×3=45. 3 faces so 45×3= 135
120+135=255
36+27=63
255+63=318
answer =318
9.2 (b) is the answer hope this helped!
Answer:
Rate of change for the linear relationship modeled is 
Step-by-step explanation:
As the there is a linear relationship in the points, so all these points will be on a single straight line. Hence the slope will be same throughout all the points.
We know that, the slope of the line joining (x₁, y₁) and (x₂, y₂) is,

Putting the points as (-1, 10) and (1, 9), we get



Rate of change is the slope of the line joining all these points.
X - y = 5....x = 5 + y
6x = 8y
6(5 + y) = 8y
30 + 6y = 8y
30 = 8y - 6y
30 = 2y
15 = y
x - y = 5
x - 15 = 5
x = 15 + 5
x = 20
ur 2 numbers are : 20 and 15
