Question

simplify the expression:
(-2z + 9)(4) =
save answer

Explanation:

Step1: Apply distributive property

We use the distributive property \(a(b + c)=ab+ac\). Here, \(a = 4\), \(b=-2z\) and \(c = 9\). So we have \(4\times(-2z)+4\times9\).

Step2: Calculate each term

Calculate \(4\times(-2z)=-8z\) and \(4\times9 = 36\). Then combine the terms.

Answer:

\(-8z + 36\)
