John read 1/3 of his book on the first day and 1/4 of the book on the second day. What fraction of the book does John have left to read?

5/12

Step-by-step explanation:

The whole book is 1.

So This will be your equation.

1/3 + 1/4 = 1

4/12 +3/12 = 1

7/12 = 1

Now you minus 7/12 from 1

1-7/12 is how much is left

12/12-7/12= 5/12

Step-by-step explanation:

Let b be the book

1/3b is the amount he finished on the first day

1/4b is the amount he finished on the second day

b - (1/3b + 1/4b) is how much he has left

b- (4/12b + 3/12b)       make the denominators the same

b- 7/12b                       add the fractions

5/12b                          The answer

John has 5/12 of the book to finish

I am sorry if this isn't the answer you wanted

But I hope this helps in someway

idk this answer sorry cant on this one.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
