Simplify the expression 4m+5+2m-1 The Correct Answer and Explanation is: To simplify the expression 4m+5+2m−14m + 5 + 2m – 14m+5+2m−1, we need to combine like terms. Step 1: Identify like terms Step 2: Combine like terms Step 3: Write the simplified expression After combining like terms, we have: 6m+46m + 46m+4 This is the

Factor each expression using the greatest common factor. 8x – 28; 12x + 15 The Correct Answer and Explanation is: To factor both expressions using the greatest common factor (GCF), we need to find the largest factor that divides all the terms in the expression. Expression 1: 8x−288x – 288x−28 Expression 2: 12x+1512x + 1512x+15
