Question

1. which expression is equivalent to -3(x + 2)=-7? (-3)x + 2=-7 (-3)x+(-3)2=(-3)(-7) (-3)x+(-3)2=-7 (-3)x+(-3 + 2)=-7

Explanation:

Step1: Apply distributive property

The distributive property \(a(b + c)=ab+ac\). For \(-3(x + 2)\), we have \(-3\times x+(-3)\times2\). So \(-3(x + 2)=-7\) is equivalent to \((-3)x+(-3)2=-7\).

Answer:

\((-3)x+(-3)2=-7\)
