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.

Forty is 25% of what number?
muminat
25 is equal to 1/4
to find 1/4 of a number, you divide the number by 4.
the equation here is:
x ÷ 4 = 40
to solve, do 40 x 4 = 160
x = 160

40 is 25% of 160
