What is the formula to calculate the total earnings of two people working the same hours at different pay rates?

Back

Total Earnings = (Hourly Rate 1 * Hours Worked) + (Hourly Rate 2 * Hours Worked) + Bonuses

Front

How do you factor the expression 24y - 36?

Back

Factor out the greatest common factor (GCF), which is 12: 12(2y - 3).

Front

What is the formula for the perimeter of a triangle?

Back

Perimeter = Side 1 + Side 2 + Side 3.

Front

If a triangle has sides of (3x + 4), (5x - 1), and (2x + 6), what is the expression for its perimeter?

Back

Perimeter = (3x + 4) + (5x - 1) + (2x + 6) = 10x + 9.

Front

What does the variable 'A' represent in the area formula A = bh?

Back

A represents the area of a shape, where b is the base and h is the height.

Front

How do you set up an equation to find the area of a rectangle?

Back

Area = Length * Width.

Front

What is the process of solving for x in an equation?

Back

Isolate x on one side of the equation using inverse operations.

Front

What is the significance of the greatest common factor (GCF) in factoring expressions?

Back

The GCF is the largest number that divides all terms in the expression, making factoring simpler.

Front

What is the relationship between the perimeter and area of a shape?

Back

Perimeter measures the distance around a shape, while area measures the space inside it.

Front

How do you determine if a factorization is correct?

Back

Multiply the factors back together to see if you get the original expression.
