which expressions are equivalent to -6n + (-12) + 4n? choose all answers that apply: a 4(n - 3) - 6n b 2(2n - 6) c none of the above
Answer
Explanation:
Step1: Simplify the given expression
Combine like - terms in (-6n+(-12)+4n). (-6n + 4n-12=-2n - 12)
Step2: Simplify option A
Expand (4(n - 3)-6n) using the distributive property (a(b - c)=ab - ac). (4(n - 3)-6n=4n-12 - 6n=-2n - 12)
Step3: Simplify option B
Expand (2(2n - 6)) using the distributive property (a(b - c)=ab - ac). (2(2n - 6)=4n-12\neq - 2n - 12)
Answer:
A. (4(n - 3)-6n)
