Hello,

Let's assume h the heigth of the parallelogram

h/6=sin 60°==>h=√3/2*6=3√3
Area=3√3 * 12=36√3

Answer:

Step-by-step explanation:

Consider ABCD is a parallelogram and AB=CD=6 and BC=DA=12, Let AE be the height of the parallelogram, then from ΔAED, we have

\frac{AE}{AD}=sin60^{\circ}

⇒\frac{AE}{12}=\frac{\sqrt{3}}{2}

⇒AE=6\sqrt{3}

Then, the area of parallelogram=Base{\times}height

=CD{\times}AE

=6{\times}6\sqrt{3}

=36\sqrt{3}sq units

Therefore, the area of parallelogram is 36\sqrt{3}sq units.

Seven times the difference of x and 4 is -10
4vir4ik [10]

Answer:

In this equation x = 2

Step-by-step explanation:

First, it is easiest to convert these words to numbers. That would make it

4 - <em>x  </em>· 7 = -10

First subtract 4 from both sides.

4 - <em>x</em> · 7 - 4 = - 10 - 4

Then you simplify.

-<em>x ·</em> 7 = -14

Divide both sides by 7.

\frac{-x(7)}{-7} = \frac{-14}{-7}


Then you simplify that fraction to 2 and thats how you get your answer.
