Is the circle inside the hexagon or hexagon inside the circle?
nexus9112 [7]

It could be either, we need more info. How big are each? If it doesn't say, then it's a trick question. Throw Schrodinger's cat at it or something.

X/2-1/5=x/3+1/4<br>solve this equation ​
Alekssandra [29.7K]

Answer:

x=\frac{27}{10}

Step-by-step explanation:

\frac{x}{2}-\frac{1}{5}=\frac{x}{3}+\frac{1}{4}

\frac{x}{2}-\frac{1}{5}-\frac{x}{3}=\frac{x}{3}+\frac{1}{4}-\frac{x}{3}

-\frac{1}{5}+\frac{x}{6}=\frac{1}{4}

-\frac{1}{5}+\frac{x}{6}+\frac{1}{5}=\frac{1}{4}+\frac{1}{5}

\frac{x}{6}=\frac{9}{20}

\frac{6x}{6}=\frac{9\times \:6}{20}

x=\frac{27}{10}

Which relationship is always true for the angles r, x, y, and z of triangle ABC?
mariarad [96]

That's the second one,


180 - x = r


Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.


The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.

If g(x)=7x²−4x−3 and h(x)=5x²−12x, find (h∘g)(1)<br><br><br>FIRST BEST ANSWER BRAINLIEST
AURORKA [14]

Answer: See below

Step-by-step explanation:

h\:\circ \:g=h\left(g\left(x\right)\right)

=5\left(7x^2-4x-3\right)^2-12\left(7x^2-4x-3\right)

=5\left(7x^2-4x-3\right)\left(7x^2-4x-3\right)-12\left(7x^2-4x-3\right)

=245x^4-280x^3-130x^2+120x+45-84x^2+48x+36

Simplify:

=245x^4-280x^3-214x^2+168x+81
