ANSWER

2x+11=20

EXPLANATION

Let the number be x.

Two times this number is 2x

If 11 is added to two times the number, the expression becomes;

2x+11

If the result is 20, then we equate the expression to 20 to get:

2x+11=20

The correct choice is the last option;

Answer:

 a - b2

Step-by-step explanation:

STEP  1 :

Trying to factor as a Difference of Squares:

1.1      Factoring:  a-b2  

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 :  a1   is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares

Final result :

 a - b2

I think the answer is 5 because you add the 1/2 and the other 1/2 leave the for alone that will give you 5 Example: 1/2+1/2=1+4=5
