Question

Algebraic expressions are polynomial y + 1by y

Answer 1

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.
