2(c-5)-2=8+c

We simplify the equation to the form, which is simple to understand
2(c-5)-2=8+c

Reorder the terms in parentheses
+(+2c-10)-2=8+c

Remove unnecessary parentheses
+2c-10-2=+8+c

We move all terms containing c to the left and all other terms to the right.
+2c-1c=+8+10+2

We simplify left and right side of the equation.
+1c=+20

We divide both sides of the equation by 1 to get c.
c=20

Answer:

600

Step-by-step explanation:

So lets rememer the formula for volume of a pyramid to sovle this:

LxHxW/3

Now lets plug in our values, for L, H, and W.

15x12x10/3

So, 15x12x10 is 1800. That is the height times the length times the width.

Now, since this isnt volume of a cube, we must divide the total my 3. This is how you find the volume of a pyramid, as I said above.

So it should be:

1800/3

=

<u>600</u>

This is your answer.

I hope this helps : )

Good luck!

If cosx=1/12 and sinx&gt;0 find tan2x
Liono4ka [1.6K]
cosx=\frac{1}{12}\\\\sin^2x+cos^2x=1\\\\sin^2x+\left(\frac{1}{12}\right)^2=1\\\\sin^2x+\frac{1}{144}=1\\\\sin^2x=1-\frac{1}{144}\\\\sin^2x=\frac{144}{144}-\frac{1}{144}\\\\sin^2x=\frac{143}{144}\\\\sinx=\sqrt\frac{143}{144}\\\\sinx=\frac{\sqrt{143}}{12}


tan2x=\frac{sin2x}{cos2x}\\\\sin2x=2sinxcosx;\ cos2x=cos^2x-sin^2x\\\\sin2x=2\cdot\frac{\sqrt{143}}{12}\cdot\frac{1}{12}=\frac{2\sqrt{143}}{144}\\\\cos2x=\left(\frac{1}{12}\right)^2-\left(\frac{\sqrt{143}}{12}\right)^2=\frac{1}{144}-\frac{143}{144}=-\frac{142}{144}\\\\tan2x=\frac{2\sqrt{143}}{144}:\left(-\frac{142}{144}\right)=-\frac{2\sqrt{143}}{144}\cdot\frac{144}{142}=-\frac{\sqrt{143}}{71}
