Question

Select all expressions that are equivalent to 6x+1−1(3x−1) . a. 6x+1−3x−1a. 6 x plus 1 minus 3 x minus 1 b. 6x+(−3x)+1+1b. 6 x plus open paren negative 3 x close paren plus 1 plus 1 c. 3x+2c. 3 x plus 2 d. 6x−3x+1−1d. 6 x minus 3 x plus 1 minus 1 e. 6x+1+(−3x)−(−1)

Answer 1

c. 3x + 2( 3 x plus 2 )

d. 6x − 3x+ 1 −1(6 x minus 3 x plus 1 minus 1)

Explanation:

We are given the expression:

6x+1−1(3x−1) .

Solving this expression:

6x + 1 - 3x +1

Collect like terms

6x - 3x +1 +1

3x + 2

Hence, the expression that are equivalent to 3x + 2 are:

c. 3x+2( 3 x plus 2 )

d. 6x−3x+1−1(6 x minus 3 x plus 1 minus 1)
