What is the discriminant of the quadratic equation 0 = –x2 + 4x – 2?
a. -4
b. 8
c. 12
d. 24

The discriminant is the part of the quadratic equation that is in the square root, which is b^2-4*a*c, where 0 = ax^2+bx+c
a is -1
b is 4
c is -2
determinant = 4^2-4*-1*-2 = 16-8 = 8, so B is the answer

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
