1*12 + 2*2 + 3*6 = 12 + 4 +18 = $34
Answer:
466 
Step-by-step explanation:
Ok to solve this problem we need to find the volume of the rectangular prism and subtract the volume of the cube from it.
The volume of the rectangular prism is Length * Width * Height.
L = 15
W = 9
H = 4
15 * 9 * 4 = 530 
The volume of the cube is 
= 4
4^3 = 64
530-64 = 466 cm^3
A) counterclockwise rotation about the origin by 90 degrees followed by a reflection about the x-axis
Answer:
x = -9
Step-by-step explanation:
6x-22+2x=8x-4
so first you want to add 4 to both sides so it becomes 6x-18=8x now substract 6x from both sides to get -18=2x now divide that by 2 and you get x= -9
