Answer:
it is -x^3 + 7x^2 -2x if you meant subtract 2x^3 - 4x^2 But if you meant subtract. 2x^3 - 4x +2 then the answer is -x^3 +3x^2 +2x -2
Step-by-step explanation:
Discriminant of a quadratic equation can be calculated as:
Discriminant = b² - 4ac
b = coefficient of x term = 2
a = coefficient of squared term = 1
c = constant = 7
So,
Discriminant = 4 - 4(1)(7) = -24
So, the correct answer to this question is option C
20 boys signed up
# of girls who signed up was 195% of the number of boys who signed up
Find 195% of 20:
1.95 * 20 = 39
So 39 girls signed up.
To find out what percent of girls who signed up for the play attended the auditions, divide 26 to the total number of girls who signed up:
26 / 39 = 0.666666667
Multiply by 100:
0.666666667 * 100 = 66.6666667%
So approximately 66.67% or 66 2/3%
