One can take the price of the item before the discount is applied and subtract that from the percentage off and get the cost of the item.
I find this is the most effective way.
another method could be if one turned the percentage into a decimal it could be subtracted from the cost of the item.
That trinomial can't be factored. You would have to complete the square to factor it and even then your answer would be an imaginary number.
x² + x + 12 = 0
x² + x = - 12
x² + x + 1/4 = - 12 + 1/4
x² + x + 1/4 = - 11 3/4
x² + x + 1/4 = - 47/4
(x + 1/2)² = - 47/4
x + 1/2 = +/- √(- 47/4)
x + 1/2 = +/-

x = 1/2 +/-

If the constant was a negative, it would be factor-able (is that a word?).
You can use a calculator but the answer is 52.065.
The measure of the largest angle is 75 degrees.
<h3>What is a triangle? </h3>
A triangle is a polygon with three sides and vertices. The sum of angles in a triangle is 180 degrees. Types of triangles include: right-angled triangle, isosceles triangle, equilateral triangle and scalene triangle.
<h3>What is the measure of the largest angle? </h3>
The measure of the largest angle = (largest ratio / sum of ratios) x 180
10 / 24 x 180 = 75 degrees
