Question

question 3
simplify the following expression
-4(7 + 5x)

Explanation:

Step1: Apply the distributive property

To simplify \(-4(7 + 5x)\), we use the distributive property \(a(b + c)=ab+ac\), where \(a = - 4\), \(b = 7\) and \(c = 5x\).
So we have \(-4\times7+(-4)\times(5x)\)

Step2: Calculate each term

Calculate \(-4\times7=-28\) and \(-4\times(5x)=-20x\)
Then combine the terms: \(-28-20x\)

Answer:

\(-28 - 20x\)
