Question

Which expression represents the expression 20 x − 10 20 ⁢ x - 10 after it has been factored completely? A. 2 ( 10 x − 5 ) 2 ⁢ ( 10 ⁢ x - 5 ) B. 2 ( 2 x − 1 ) 2 ⁢ ( 2 ⁢ x - 1 ) C. 10 ( 20 x − 10 ) 10 ⁢ ( 20 ⁢ x - 10 ) D. 10 ( 2 x − 1 ) 10 ⁢ ( 2 ⁢ x - 1 )

Answer 1

A. 2 ( 10 x − 5 )

D. 10 ( 2 x − 1 )

Explanation:

Given expression:

20x − 10

Find the equivalent expression

Check all that applies

A. 2 ( 10 x − 5 )

= 20x - 10

B. 2 ( 2 x − 1 )

= 4x - 2

C. 10 ( 20 x − 10 )

= 200x - 100

D. 10 ( 2 x − 1 )

20x - 10

The correct options are

A. 2 ( 10 x − 5 )

D. 10 ( 2 x − 1 )
