With these 2 questions asap after cruising at 750 feet below the surface of the ocean, a submarine rises 325 feet. how many more feet must they rise in order to reach the surface? second question a has one triangular base and three triangular lateral faces. choices: rectangular prism, triangular prism, triangular pyramid, square pyramid

Question 1.

750 ft - 325 ft = 425 ft

Question 2.

triangular pyramid

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

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
