Answer:

This is not possible

Step-by-step explanation:

The only way you get this is if you plug it into the calculator without placing parenthesis around -4

For example:

-4^2 = -16 while (-4)^2= 16

When doing math it is common knowledge that when two negative numbers are multiplied together the negative sign will cancel out and turn into a positive product.

Also -4*-4 is the same as -4^2 just written differently

One of the sides of an equilateral triangle is 32. What is the height of the triangle? Round to 2 decimal places.

Ilya [14]

So because it's an equilateral triangle, you can cut the triangle in half and make a right triangle with a hypotenuse of 32. The bottom of the triangle would be half of 32, which is 16, because you cut the triangle in half. Now you can use the pythagorean theorem to solve for the height.

$16^{2} +b^{2} =32^{2}$

The answer is whatever b is:

b = $\sqrt{ 32^{2} - 16^{2}$

So your answer is 27.713.
