Use a graphing calculator and a system of equations to find the roots of the equation.
X4– 4x² = 6x² – 12x
From least to greatest, what are the integral roots
of the equation?

The answer above is correct ( -2 & 0)

The answer to the next part is

- D. 1.27

- E. 4.73

Step-by-step explanation:

I got this correct on Egd. 2021

(Also, the question above should be written as "x4 − 4x3 = 6x2 − 12x

From least to greatest, what are the integral roots of the equation?" it is 4x cubed, not squared)

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
