What is the solution to the equation?

Oxana [17]

ANSWER

(C) d=1

EXPLANATION

The given equation is

$\frac{ - 3d}{ {d}^{2} - 2d - 8} + \frac{3}{d - 4} = \frac{ - 2}{d + 2}$

Factor the first fraction to get,

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

Multiply through by (d+2)(d-4)

$- 3d + 3(d + 2) = - 2(d - 4)$

Expand:

$- 3d + 3d + 6 = - 2d + 8$

$6 = - 2d + 8$

$6 - 8= - 2d$

$- 2 = - 2d$

divide both sides by -2

$d = 1$

Use inductive reasoning to predict the next three numbers in the pattern.

Mademuasel [1]

The next three numbers in the pattern would be 768, -3072, 12,288.

<h3>What are the next three numbers?</h3>

Looking at the given sequence, it can be seen that the numbers increase by a multiple of 4.

-12 /3 = 4

48 / 12 = 4

192 / 48 = 4

The next three numbers would be:

192 x 4 = 768

768 x 4 = 3072

3072 x 4 = 12,288.

Examining the numbers, it can be seen that the positive and negative signs alternate. Thus, the numbers would be : 768, -3072, 12,288.
