Which expression is equivalent to 3x(x2-2)?

What is the probability that the equipment that the equipment lasts at least 100 hours

Given: -3x - (x-1) + 3/2(3x+3)

Step One: Distribute the negative into the (x-1), changing the sign of each term.

-3x - x + 1 + 3/2(3x+3)

Step Two: Distribute the 3/2 into the (3x+3). Remember to multiply both terms by 3/2

-3x - x + 1 + 9x/2+ 9/2

Step Three: To make the numbers easier to deal with, convert the fractions to decimals (9/2 = 4.5)

-3x - x + 1 + 4.5x + 4.5

Step Four: Combine Like Terms (YOU CAN DO THIS BIT BY BIT THROUGHOUT PREVIOUS STEPS).

0.5x + 5.5

Step Five: Now that you have found your equation, convert back to fractions and you'll have the answer.

1/2x + 11/2
