Q. Factor 72y+108z to identify the equivalent expressions.Choose 2 answers:(A) 9(7y+12z)(B) 36(2y+3z)(C) 6(18y+12z)(D) 12(6y+9z)
Identify GCF: Step Title: Identify the Greatest Common Factor (GCF)Concise Step Description: Determine the greatest common factor of the terms in the expression.Step Calculation: The GCF of 72y and 108z is 36, since 36 is the largest number that divides both 72 and 108.
Factor Out GCF: Step Title: Factor Out the GCFConcise Step Description: Factor out the GCF from the expression.Step Calculation: Factoring out 36 from 72y gives 36×2y, and factoring out 36 from 108z gives 36×3z. So, the factored expression is 36(2y+3z).
Verify Factored Expression: Step Title: Verify the Factored ExpressionConcise Step Description: Check if the factored expression is equivalent to the original expression.Step Calculation: Multiplying the factored expression 36(2y+3z) gives 36×2y+36×3z, which simplifies to 72y+108z, the original expression.
Compare with Answer Choices: Step Title: Compare with the Answer ChoicesConcise Step Description: Compare the factored expression with the given answer choices.Step Calculation: The factored expression 36(2y+3z) matches with choice B. To check for another equivalent expression, we can look for a factor of 36 that is also a factor of the coefficients in the expression 2y+3z. Since 9 is a factor of 36, we can rewrite the expression as 9(8y+12z), which simplifies to 9(8×y+12×z). However, this does not match the original coefficients of 2y and 3z, so there is no other equivalent expression among the choices.
