Answer:

32

Step-by-step explanation:

Since there are 20 total pieces of gum, we divide 20 by 5 to figure out how many groups of 8 pieces of candy there are (For every 8, 5 are gum). This gives us 4 groups of 8. Because for every 8 pieces, 5 are gum, we subtract 5 from 8 and get three. Multiply 3 by 4 (the number of groups), and we get 12 other pieces of candy. Add to 20, and we get 32. To check, divide 32 by the number of groups (4) and we get 8, which is how many pieces of candy are in each group.

Find the greatest common factor.<br> 2y^3, 8y
Ira Lisetskai [31]

Answer:

STEP1:Equation at the end of step 1

2y3 - 8y

STEP2:

STEP3:Pulling out like terms

 3.1     Pull out like factors :

   2y3 - 8y  =   2y • (y2 - 4) 

Trying to factor as a Difference of Squares:

 3.2      Factoring:  y2 - 4 

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

         A2 - AB + BA - B2 =

         A2 - AB + AB - B2 =

         A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check :  y2  is the square of  y1 

Factorization is :       (y + 2)  •  (y - 2) 

Final result :

2y • (y + 2) • (y - 2)
