While scuba diving rajeev dove to a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet

what expression can be use to find rajeev new position

12.6 - 8.7

-12.6 - 8.7

-12.6 - (-8.7)

12.6 - (-8.7)

Option B is the correct answer.

Step-by-step explanation:

Scuba diving Rajeev dove to a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet

Depth Rajeev dove = 12.6 feet.

Descended depth after dive = 8.7 feet

Total depth = 12.6 + 8.7

Since this is depth the sign of the position is negative.

Rajeev's new position = - ( 12.6 + 8.7) = -12.6 - 8.7

Option B is the correct answer.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

probably the last option
