simplify to create an equivalent expression.\n2(3r + 7)-(2 + r)\nchoose 1 answer:\na 4r + 12\nb 5r + 13\nc 5r + 12\nd 5r - 12
Answer
Explanation:
Step1: Apply distributive property
$2(3r + 7)=2\times3r+2\times7 = 6r + 14$ and $-(2 + r)=-2 - r$
Step2: Combine like - terms
$(6r + 14)+(-2 - r)=(6r-r)+(14 - 2)$ $6r-r=5r$ and $14 - 2 = 12$
Answer:
C. $5r + 12$
