Step-by-step explanation:
x^2 + 10x = -25
x^2 + 10x + 25 = 0
（x+5)^2=0
x=－5
The probability that both of the students are on Team D is about 5.56%
There are 4 teams, so the first person has a 1/4 chance of being on Team D.
However, for the second person, there are only 6 spots left out of 27 to be on Team D.
To find the combined probability, we need to multiply the two fractions.
1/4 times 6/27 = 1/18 or about 5.56%

Answer:
162 degrees
Step-by-step explanation:
Angles P and F are supplementary, so ...
3x^2 +12x = 180
x^2 +4x = 60
x^2 +4x -60 = 0
(x +10)(x -6) = 0
The useful value of x that makes this true is x=6.
The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:
∠S = 180° -18° = 162°
The measure of one of its angles is 150°. The correct option is D.
<h3>How to calculate the angle?</h3>
The value of angles in a polygon is calculated by using the formula:
= (n - 2) × 180°
where n *+ number of sides
This will be illustrated as:
= (n - 2) × 180°
= (12 - 2) × 180°
= 10 × 180°
= 1800°
Since it has 12 sides, the value of each angle will be:
= Total angle / Total sides
= 1800° / 12
= 150°
The angle is 150°.
