Whats the solution of x^2+4x-4=8

denpristay [2]

Answer:

x = 2, x = -6

Step-by-step explanation:

$x^2+4x-4=8$

Subtract 8 from both sides.

$x^2+4x-4-8=8-8$

Simplify.

$x^2+4x-12=0$

Solve with quadratic formula.

a = 1

b = 4

c = -12

I do not have time to show work for quadratic formula parts.

I am so sorry for this inconvenience.

How many terms are there in a geometric series if the first terms is 2, the common ratio is 4, and the sum of the series is 2,73

arsen [322]

The sum of n terms of a geometric series is given by
$S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}$

Substituting the given numbers, you have
$2730=2\dfrac{4^{n}-1}{4-1}\\\\2730\dfrac{3}{2}=4^{n}-1\\\\4096=4^{n}\\\\\dfrac{\log(4096)}{\log(4)}=n=6$

There are 6 terms in the series.
