Final answer:
To simplify the expression –7(–4 + s), you can distribute the –7 to both the –4 and s inside the parentheses and simplify the expression to 28 - 7s.
Step-by-step explanation:
To simplify the expression –7(–4 + s), we can use the distributive property of multiplication over addition. We distribute the –7 to both the –4 and s inside the parentheses.
When we multiply a negative number by a negative number, the result is positive. So, -7 times -4 is 28, and -7 times s is -7s.
Therefore, the simplified expression is 28 - 7s.
