Select the correct answer from each drop-down menu. The expression gives the same value as (3x − 2x) + 2(2x − x) + 4 for both x = 1 and x = 3. So, the two expressions are(equivalent or not equivalent .
a. 2(x+x)-2
b. x + 2(x + 2)
c. 2x - ( x+1 )
d.2 x - x + 4

b. x + 2(x + 2) = x+2x +4 =3x+4

Step-by-step explanation:

simplify expression

(3x − 2x) + 2(2x − x) + 4 =

x + 2x + 4 =

3x+4

if x= 1 then 3x+4 =3*1+4 =3+4 = 7

if x= 3 then 3x+4 =3*3+4 =9+4 = 13

now that means when you plug in in given expressions 1 and 3 answers should be 7 and 13

or when you simplify expression it should be 3x+4 and that's b.

Step-by-step explanation:

We are looking for an expression equivalent to when

Testing all the alternatives:

This is not the equivalent expression

This is an equivalent expression
