Question

simplify the expression: -4(-0.4s + 3) = save answer

Explanation:

Step1: Apply the distributive property

We use the distributive property \(a(b + c)=ab+ac\), here \(a = - 4\), \(b=-0.4s\) and \(c = 3\). So we have \(-4\times(-0.4s)+(-4)\times3\).

Step2: Calculate each term

First term: \(-4\times(-0.4s)=1.6s\) (because multiplying two negative numbers gives a positive number, and \(4\times0.4 = 1.6\)).
Second term: \(-4\times3=-12\) (multiplying a negative and a positive number gives a negative number).

Step3: Combine the terms

Combining the two terms we got, the simplified expression is \(1.6s-12\).

Answer:

\(1.6s - 12\)
