=9 x (396 x + 268) + 2 (396 x + 268)

=9 * 396 x x+2 * 396 x+9 * 268 x+2 * 268

=3564 x^2 + 3204 x + 536

(x^2+2)(x+8) (or) (x^3+5)(x+6) (or) (x+2)(x+8)(x+6)

Madeleine owes $36,000 to a private lender. The debt grows with 12% annual interest that compounds every week. How much will Mad

viva [34]

Answer:

A= $40584.28

Step-by-step explanation:

P = 36000

r = 12% = 0.12

n = 52 weeks

t = 1

$A = P(1 + \frac{r}{n})^{nt}\\$

$=36000(1 + \frac{0.12}{52})^{52 \times 1}\\\\=36000 (1.002307)^{52}\\\\=36000 \times 1.12734\\\\=40584.28$

Consider 8x2 - 48x = -104.

ki77a [65]

Answer:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

We have the equation:

$8x^2-48x=-104$

Divide by 8:

$x^2-6x=-13$

Now complete the squares so the left side is a perfect square of a binomial:

$x^2-6x+9=-13+9=-4$

Factoring the perfect square:

$(x-3)^2=-4$

Taking the square root:

$x-3=\sqrt{-4}$

The square root of a negative number is an imaginary number:

$x-3=\pm 2\mathbf{i}$

Solving for x:

$x=3\pm 2\mathbf{i}$

The solutions are:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$
