PLEASE HELP!
sesenic [268]

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!

Y = 4x+1 y=x^2 + 2x - 2 A.6,2 B. 2,6 C. -6,2 D. -6,-2
natta225 [31]

Answer:

The solution is (3,13) and (-1,-3). So none of the mentioned options is correct.

Step-by-step explanation:

Given that

y = 4x + 1  (i)

y = x^2 + 2x -2 (ii)

Now, by susbstituting the value of 'y' from equation i to equation ii, we get

4x+1=x^2 + 2x -2

0=x^2 + 2x -2-4x-1

0=x^2 + (2x -4x) +(-2-1)

0=x^2 + (-2x) +(-3)

0=x^2 -2x -3

x^2 -2x -3 = 0 (iii)

Now by factorization, equation iii can be written as

x^2 -3x +x -3 = 0

x(x -3) + 1(x -3) = 0

(x -3)(x +1) = 0

x = 3 and x = -1

By putting the values of x in equation i, we get

y = 4(3) + 1

y = 12 +1

y = 13

and

y = 4(-1) + 1

y = -4 +1

y = -3

Therefore, the solution is (3,13) and (-1,-3). So none of the mentioned options is correct.
