Answer:

Correct option is B

Step-by-step explanation:

Note that

[tex]20x^2y=2\cdot 2\cdot 5\cdot x\cdot x\cdot y,[/tex]

[tex]56x^3=2\cdot 2\cdot 2\cdot 7\cdot x\cdot x\cdot x.[/tex]

If the mystery term is [tex]22x^3=2\cdot 11\cdot x\cdot x\cdot x,[/tex] then the

[tex]GCF(20x^2y,56x^3,22x^3)=2\cdot x\cdot x=2x^2.[/tex]

If the mysteyr term is [tex]24x^2y=2\cdot 2\cdot 2\cdot 3\cdot x\cdot x\cdot y,[/tex] then

[tex]GCF(20x^2y,56x^3,24x^2y)=2\cdot 2\cdot x\cdot x=4x^2.[/tex]

If the mysteyr term is [tex]26x^2y=2\cdot 13\cdot x\cdot x\cdot y,[/tex] then

[tex]GCF(20x^2y,56x^3,26x^2y)=2\cdot x\cdot x=2x^2.[/tex]

If the mysteyr term is [tex]28y^3=2\cdot 2\cdot 7\cdot y\cdot y\cdot y,[/tex] then

[tex]GCF(20x^2y,56x^3,28y^3)=2\cdot 2=4.[/tex]

Thus, correct option is B

Answer:

option (B) is correct.

Mystery term has to be [tex]24x^2y[/tex]

Step-by-step explanation:

 Given : [tex]4x^2[/tex] is the GCF of the polynomial [tex]20x^2y + 56x^3 - ?[/tex]

We have to find the mystery term '?'

GCF stands for greatest common factor. GCF is the highest common factor that can divide all the given terms.

Here, [tex]4x^2[/tex] is the GCF of the polynomial [tex]20x^2y + 56x^3 - ?[/tex]

For unknown term , we have two conditions,

1) it has to be multiple of 4

2) it must have [tex]x^2[/tex] as a factor.

So out of given options only [tex]24x^2y[/tex] is a term which is both multiple of 4 and has [tex]x^2[/tex] as a factor.

Thus, Mystery term has to be [tex]24x^2y[/tex]

Thus, option (B) is correct.
