6 0

Answer:

The answer for this question is C, E and F .

Step-by-step explanation:

Given that the length is 3 times the width. So firstly, you have to find the expression of length :

length = 3 \times width

Let width = w,

length = 3 \times w

length = 3w

Next, the perimeter of rectangle is P = 2(length+width) so you have to substitute the expression into the formula :

p = 2(length + width)

Let length = 3w,

Let width = w,

p = 2(3w + w) \:  \: (option \: e)

p = 2(3w) + 2(w) \:  \: (option \: f)

p = 6w + 2w

p = 8w \:  \: (option \: c)

A shark is 80 feet below the surface of the water. It swims up and jumps out of the water to a height of 15 feet above the surfa
lyudmila [28]

Answer:

∆y = 95 ft

the vertical distance the shark travels is 95 ft

Step-by-step explanation:

Given;

Initial position y1= 80 ft below the surface of water = -80ft

Final Position y2 = 15 ft above the surface = +15ft

The vertical distance travelled by the shark is;

∆y = y2 - y1 = 15 - (-80) ft

∆y = 15 +80 ft

∆y = 95 ft

the vertical distance the shark travels is 95 ft
