Answer:

d=1

Step-by-step explanation:

Factor d^2 - 2d - 8 into (d-4)(d+2)

Move -2/d+2 onto the other side, changing it into 2/d+2.

\frac{-3d}{(d-4)(d+2)} +\frac{3}{d-4}+\frac{2}{d+2} = 0

Let the empty side equal zero.

Add 3/d-4 and 2/d+2

\frac{5d-2}{(d+2)(d-4)}

Then add that to -3d.

\frac{2d-2}{(d+2)(d+4)}

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.

2d=2

d=1

I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.

Suppose a car's momentum is calculated to be 36000 . The mass of the car is 1,500 kg. What is the magnitude of the velocity of t
Ad libitum [116K]

Answer:

The magnitude of the velocity of the car is 24 m/s .

Step-by-step explanation:

Given : A car's momentum is calculated to be 36000 .

          the mass of the car is 1500 kg.

To find: What is the magnitude of the velocity of the car.

Formula used:

           Momentum =mass × velocity

Explanation:

We are given that momentum of the car =36000 .

                                  Mass of the car = 1500 kg .

  Plugging the given value in the above formula

                 Momentum =mass × velocity

                               36000 = 1500 × velocity

  On dividing both side by 1500 we get ,

                              velocity   =    24 meter/second

Therefore,   The magnitude of the velocity of the car is 24 m/s .

Each glass vase at a Mother’s Day brunch has 8 stems, of which 37.5% are stems of greenery. How many stems of greenery are in ea
ella [17]
I believe the answer is there are 3 stems of greenery in each vase.

You just do 8 times 37.5% or 0.375 and get 3.
