Factor each trinomal

-6x^2-9

-2x^2+22x-48

-3 (2 x^2 + 3)

-2(x - 3) (x - 8)

Step-by-step explanation:

Factor the following:

-6 x^2 - 9

Factor -3 out of -6 x^2 - 9:

 -3 (2 x^2 + 3)

Factor the following:

-2 x^2 + 22 x - 48

Factor -2 out of -2 x^2 + 22 x - 48:

-2 (x^2 - 11 x + 24)

The factors of 24 that sum to -11 are -3 and -8. So, x^2 - 11 x + 24 = (x - 3) (x - 8):

-2(x - 3) (x - 8)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
