A,C,D

"B" is definitely not the answer because the fraction isn't negative but the decimal is negative which isn't right.

-30 = -16 + N what is he answer to this

marta [7]

Answer:

Step-by-step explanation:

To solve for the given variable $N$ , we need to get $N$ on one side of the equation by itself. To do so, we need to remove the -16 that is on the same side of the variable.

To get rid of the -16, we can add a 16 to that side of the equation since $-16 + 16 = 0$ , which will get $N$ by itself; however, if we add -16 to one side of the equation, we must add it to both sides of the equation:

$-30 + 16 = -16 + 16 + N$

$-14 = N$

Solve 3x2 = −12x − 15. x = −4 ± 2i x = −4 ± i x = −2 ± 2i x = −2 ± i

diamong [38]

ANSWER

$x = - 2 \pm i$

EXPLANATION

We use the method of completing the squares.

The equation is
$3 {x}^{2} = - 12x - 15$

We rewrite the above equation to obtain;

$3 {x}^{2} + 12x = - 15$

We divide through by 3 to obtain;

${x}^{2} + 4x = - 5$

We add half the coefficient of
$x$

to both sides of the equation to get,

${x}^{2} + 4x + {2}^{2} = - 5 + {2}^{2}$

The right hand side is now a perfect square.

${(x + 2)}^{2} = - 1$

We now take square root of both sides to get;

$x + 2 = \pm \sqrt{ - 1}$

We add -2 to both sides,

$x = - 2 \pm \sqrt{ - 1}$

We simplify to obtain,

$x = - 2 \pm i$
