A deep sea diver is at 45 feet below sea level. A helicopter is at 100 feet above sea level. What is the distance between the helicopter and deep sea diver?

D = 55 feet

Step-by-step explanation:

Let below sea level is negative direction and above sea level is positive direction.

A deep sea diver is at 45 feet below sea level = -45 feet

A helicopter is at 100 feet above sea level = +100 feet

We need to find the distance between the helicopter and deep sea diver. It can be calculated by simply adding the above data as follows:

D = -45 +100

= 55 feet

Hence, the distance between the helicopter and deep sea diver is 55 feet.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
