Algebraic expressions are polynomial y + 1by y

Answer»

Step-by-step explanation:

Here, we can use them to group 4 and 2—the numbers being added. This is the CORRECT way to WRITE the expression. Based on the order of OPERATIONS, always solve operations in parentheses first. Here, you'd add 4 + 2, then multiply that sum by 5—in other words, exactly what was written in the ORIGINAL expression.
