What is her total change in height over 3 years? . : )

In the time period of three years, she would shrink .75 cm or 3/4 cm.

.75

Step-by-step explanation:

1/4 + 1/4= a half .5 so .5+1/4= .75

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
