In order to find out what 36x + 9 is equivalent to,, we must factor out 9 from the expression. Once we do this you will find that this expression is equivalent to 9(4x + 1),, or option E. Next we will look at the expression 9(4x -1). In order for us to find out the equivalent to this expression,, we must first multiply each term in the parenthesis by 9. 9 × 4x - 9 Now calculate the product 36x - 9 This means that the equivalent for this expression is 36x - 9,, or option A. Lastly,, we will look at the final expression given which is 4(9x + 2). The first step for finding the equivalent of this expression is to multiply the numbers in the first parenthesis together. (36x) + (4 × 2) Now multiply the numbers in the second parenthesis together. (36x) + 8 Remove the parenthesis 36x + 8 Now factor out 4 from the expression to get your final answer. 4(9x + 2) This means that the last expression is equivalent to 4(9x + 2),, or option C. Let me know if you have any further questions :)
