Answer:
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.
