When the marginal benefits of a decision is equal to the marginal costs, it is called . (SSEF2) * 1 point equilibrium scarcity specialization a rational decision

A rational decision

Explanation:

Marginal decision involves using more than or less than what you have by comparing the cost and benefits. Marginal cost is the additional cost as a result of making a different decision while the marginal benefit is the additional benefit as a result of making a different choice.  A rational decision is a decision in which the marginal benefits as a result of taking that decision is greater or equal to the marginal cost of that decision.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.
