Twice a certain number is tripled. the resulting number is
a. 2x + 3
b. 2x - 3
c. (2x)3
d. (2x)

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the answer is d. (1.2, -4.7) on edgn

hope this !
