Can you please help me I am super stuck

a.) 12 Newtons

b.) Same Direction

c.) Unbalanced

Explanation:

The system shows 2 individual forces:

A force of 5 N pulling the box LEFT

A force of 7N pushing the box LEFT

Both forces are LEFT, so they have the same direction.

Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:

Resultant force's magnitude is then: 5N + 7N = 12N

Resultant force's direction: unchanged = LEFT

Since the resultant force's magnitude is not 0, the system is unbalanced.
