(-2.3)*4.7 would be equal to -10.81
Take the segment between the first two vertices to be the base of the triangle.
The length of the base is then 8 - 1 = 7.
The height of the triangle is then 6-2 = 4.
The area of the triangle is thus 7*4/2 = 14.
Hope that helps!
I believe it's C, that is the only one that makes sense to me

Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
The ocean floor directly beneath the boat is at a depth of = 180 meters
Submarine is at an elevation when it is above the ocean's surface = 2 meters
Total distance submarine needs to descends at a constant rate = 180+2=182 m
Rate of submarine descends = 0.4 meters per second.
Time taken by a scientist spend descending after boarding the submarine is given by
so, it must be less than 455 seconds.
therefore, it becomes x<455.
Hence, Option 'A' is correct.
