Quadrilateral is A' B' C' D' is a dilation of quadrilateral ABCD about point P with a scale factor of 3.

Enlargement because all sides are being multiplied by 3 times their original amount making if it were a scale factor that were a fraction then it would be a reduction

Solve for x in the equation x² + 14x + 17 = - 96

gavmur [86]

Answer:

Solutions of x are;

x = -7 + 8i and x = -7 -8i

Step-by-step explanation:

Given the equation: $x^2+14x+17 = -96$

Add 96 both sides we get;

$x^2+14x+17+96 = 0$

$x^2+14x+113= 0$

Using quadratic formula $ax^2+bx+c = 0$ then the solution is given by:

$x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}$

On comparing we have;

a= 1, b =14 and c =113

$x = \frac{-14\pm\sqrt{(14)^2-4(1)(113)}}{2(1)}$

$x = \frac{-14\pm\sqrt{196-452}}{2}$

$x = \frac{-14\pm\sqrt{-256}}{2}$

Simplify:

$x = \frac{-14\pm 16i}{2}$ ; where i is the imaginary, $i^2= -1$

$x = -7 \pm 8i$

Therefore, the solution of x are; x = -7 + 8i and x = -7 -8i

Joseph took out a loan from the bank to purchase a new car. The initial loan amount was for $25,000 with an interest rate of 3.5

siniylev [52]

3.5% • 5 = 17.5%

$25,000 • 17.5% = $437,500

i hope this is correct
