Explanation:</h2>
In physics, work is defined force that causes displacement. So this can be expressed by the following equation:

Where:

The force can be found as:

And for the displacement:

The force (weight) is down and the displacement is up, then the work must be negative. So:

Group A I’m pretty confident with that answer
Answer:
x = 4
Step-by-step explanation:
Using the rule of logarithms
x = n , then x = 
Given
(5 + 11x) = 2 , then
5 + 11x = 7² = 49 ( subtract 5 from both sides )
11x = 44 ( divide both sides by 11 )
x = 4
