Answer:

x=-1/2

Step-by-step explanation:

Given:

8x^3+12x^2+6x+1=0

Making factors of the given polynomial by using cube formula, given as

(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3

Re-writting the given polynomial:

(2^3.x^3) + 3(2^2.x^2)(1)+3(2x)(1) + (1^3)=0

Hence (2^3.x^3) + 3(2^2.x^2)(1)+3(2x)(1) + (1^3) can be written as (2x+1)^3

(2x+1)^3= 0

2x+1= 0

2x= -1

x= -1/2 !

A number cube is rolled 24 times and the results are recorded as follows: 2 ones, 4 twos, 7 threes, 4 fours, 3 fives, and 4 sixe

aksik [14]

I would say the answer would be 29.17% because $\frac{7}{24}$ =29.17%

Hope this helps

I'm so sorry if this is wrong

have a great day/night
