Answer:
The answer is D
Step-by-step explanation:
I did the assignment
The answer is x=9
Explanation: x + 16 = x^2 - 8x +16
x = x^2 - 8x
9x - x^2 = 0
X x (9-x) = 0
Answer:
A
Step-by-step explanation:
x+x+1+x+2=33
3x+3=33
3x=30
x=10
so x+1 =11
x+2 =12
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.
