A submarine was 144 feet below sea level. A shark was hovering at a constant depth above the submarine. The submarine’s depth was twice the depth of the shark.

Which integer expression describes the position of the shark in relation to sea level?

feet : Shark is 72 feet below sea level.

Step-by-step explanation:

Let x represent depth of the shark.

We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be .

We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be .We can represent this information in an equation as:

To find shark's position, we need to solve for x.

Therefore, feet represents shark's elevation, which represents that shark is 72 feet below sea level.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

(x+3)(x+7)
