Solve the quadratic equation (2x-3)^2 = 6(3-2x)

LenKa [72]

Answer:

$x=\frac{3\sqrt{2}-3 }{2}$

$x=-\frac{3\sqrt{2}-3 }{2}$

Step-by-step explanation:

Open the brackets first:

$4x^2+9=18-12x$

Simplify:

$4x^2+12x-9=0$

It is determined that this can't be factored, so rewrite the equation so you can complete the square.

$x^2+3x=\frac{9}{4}$

Take the square of 1.5 and add it to both sides:

$x^2 + 3x+ \frac{9}{4} =\frac{9}4} +\frac{9}{4}$

Factor:

$(x+\frac{3}{2})^2=\frac{9}{2}$

$x+\frac{3}{2} = \frac{3\sqrt{2} }{2 }$

or $x+\frac{3}{2} =-\frac{3\sqrt{2} }{2}$

So $x=\frac{3\sqrt{2}-3 }{2}$

or $x=-\frac{3\sqrt{2}-3 }{2}$

Two cities are 210 km apart. A train traveled this distance in 4 2/3 hours and then made the return trip at a speed of 50 2/5 km

AveGali [126]

$4 \frac{2}{3}= \frac{14}{3}$

So, $\frac{210km}{ \frac{14}{3}hr }= 45km/h$

$50 \frac{2}{5} = \frac{252}{5}$

So, $\frac{252}{5}/45= 1.12$ times greater on the return trip.

Help i forgot how to do this and this is one of the last questions on my summer homework

KatRina [158]

Answer:

162°

Step-by-step explanation:

They are on a straight line so add to 180

8x + 10 + 2x - 20 = 180

10x - 10 = 180

10x = 190

x = 19

We want AXB so 8x + 10 where x = 19

8(19) + 10 = 162 so it is 162°
