Which of the following is the solution to the equation - n/2 + 14 = 0 ?
poizon [28]
The answer is n=28;

1. Subtract 14 from both sides (-n/2 = -14)

2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)

3. Divide by -1 to get n by itself (n = 28)

You could also eliminate step three by multiplying by -2 instead of just 2.

Hope this helps!

What parts of the right triangle are used when applying the Pythagorean Theorem? How is it used to solve a right triangle?
Bogdan [553]
You use the equation a^2 + b^2 = c^2 and the parts include the hypotenuse which is across from the right angle(the diagonal part of the triangle) and this is also the c for the equation and the a and b are the two legs(the other lengths of the triangle) and to find one of these you plug what you know into the equation and go from there
