x+7/2=21
=x+7=2*21
=x+7=44
=x=44-7
=x=35

Answer:
E = 30.37 J
Step-by-step explanation:
Given that,
The spring constant of the spring, k = 300 N/m
The spring is stretched by 0.45 m, x = 0.45 m
We need to find the elastic energy stored in the spring. The formula for the elastic energy is given by :

So, the required elastic energy is equal to 30.37 J.
