PLEASE HELP!

Answer:

$36\sqrt{3}$

Step-by-step explanation:

Hi!

Since an equilateral triangle means that every side is equal, our triangle will have 12 on all sides.

To find the height of an equilateral triangle we use $\frac{a\sqrt{3}}{2}$ .

$\frac{12\sqrt{3} }{2} = 6\sqrt{3}$ .

So the height is $6\sqrt{3}$ .

Now we have to solve 12 * $6\sqrt{3}$ ÷ 2.

$12 \cdot 6\sqrt{3} = 72\sqrt{3}$

$72\sqrt{3}\: \div\: 2 = 36\sqrt{3}$ .

Thus, the area of the triangle is $\boxed{36\sqrt{3}}$ .

Hope this helps!

Answer:

$-5x^2+5x+1$

Step-by-step explanation:

To simplify polynomials, find the like terms which look and sound the same then combine the coefficients of each to simplify.

$(2x^2-9x+3)+(-7x^2+4x-2)\\2x^2-7x^2-9x+4x+3-2\\-5x^2+5x+1$
