Solve 3x to the <br> second power <br> -2x-8=0 using an algebraic method

MatroZZZ [7]

Answer:

$x=2\textrm{ or } x=-\frac{4}{3}$

Step-by-step explanation:

Given:

The equation is given as:

$3x^{2}-2x-8=0\\3x^{2}-6x+4x-8=0\\3x(x-2)+4(x-2)=0\\(x-2)(3x+4)=0\\\\x-2=0\textrm{ or }3x+4=0\\x-2+2=0+2 \textrm{ or }3x+4-4=0-4\\x=2\textrm{ or }3x=-4\\x=2\textrm{ or}\\x=-\frac{4}{3}$

Therefore, the possible values of $x$ are 2 and $-\frac{4}{3}$

A rectangular garden has links twice as great as it's with a second rectangular garden has the same link as the first garden and

irinina [24]

Solution :

For the bigger rectangle

Width of bigger rectangle = W

Length of bigger rectangle, L = 2W

For the smaller rectangle

Width , w = W+4

Length, l = L = 2W

Area, a =120 $m^2$

Now we know,

Area = length x width

$a=l \times w$

$120=(2W) \times (W+4)$

$120=2W^2 + 8W$

$2W^2+8W-120=0$

$W^2+4W-60=0$

$(W+10)(W-6) = 0$

We get, either $W=-10$ (rejecting)

or $W=6$

∴ length of the bigger rectangle, $L=2W$

= 2(6)

= 12 m

Length of the smaller rectangle, $L=2W$

= 2(6)

= 12 m

Hence, the length of the two gardens is 12 m.

What is the a, b, and r for y=3.6(1.25)^x

tia_tia [17]

Answer:

a=3.6, v=1.25 and r=25%

Step-by-step explanation:

The given exponential function is

$y = 3.6 {(1.25)}^{x}$

We compare to the form:

$y = a{(b)}^{x}$

We have a=3.6, b=1.25

The r is the percentage of increase or decrease.

We realized there is a 25% increase because

$y = 3.6 {(1 + 25\%)}^{x}$

Hence

$r = 25\%$
