21/2 * 1 1/6=i need can someone explain this for me?

2  11/12

Step-by-step explanation:

2 1/2 * 1 1/6

Change the mixed numbers to improper fractions

2 1/2 = (2*2+1)/2 = 5/2

1 1/6  = (6*1+1) /6 = 7/6

Replace with the improper fractions

5/2 * 7/6 = 35/12

Now we have to change it back to a mixed number

12 goes into 35 2 times   (2*12 =24)  

35 -12 = 11    with 11 left over

2 11/12

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
