Answer:
254 yds²
Step-by-step explanation:
There are 6 faces of the prism we need to calculate the area of for a rectangular prism.
The base and top of the prism measure 9x7 yards each, so there are two faces with an area of 63 yds² (9 x 7 = 63)
The sides of the prism measure 4x7 yards each, so there are two faces with an area of 28 yds² (4 x 7 = 28)
The front and back face of the prism measure 9x4 yards each, so there are two faces with an area of 36 yds² (9 x 4 = 36)
The total surface area is
2(63) + 2(28) + 2(36) = 254 yds²
Answer:
The correct answer is: Negative correlation.
Step-by-step explanation:
The negative correlation determines the relationship between two variables, it says that there is an inverse relationship between two variables, whenever one of them is decreasing, the other one increases, and it's the same in reverse.
Answer:

15 is the starting fee and it is 6$ per class so it would be 6x+15=75
Answer:
x = 5
Step-by-step explanation:
3x - 2 = x + 8
Subtract x from each side
3x-x - 2 = x-x + 8
2x -2 = 8
Add 2 to each side
2x-2+2 = 8+2
2x = 10
Divide each side by 2
2x/2 =10/2
x = 5
