Answer:
6i^2-12i
Step-by-step explanation:
3i×2i =6i^2
3i×4 =12i
The answer is choice A
The line is RS because R and S are on the line.
The plane is RSU because we need at least 3 non-collinear points to form a plane. In this case, point U is not on line RS.
Find the difference in elevations:
8720 - 6350 = 2370 feet.
Difference in mile markers: 12-7 = 5
Average change = feet / markers
2370/5 = 474
The answer is 474 feet
Directly proportional or positively correlated
Answer:
600
Step-by-step explanation:
0+.80x=60+.70x
-.70x=60-.70x
.10x=60
÷.10=÷.10
C=600
0+.80(600)=480
60+.70(600)=480
