Question

5.) If b = -2, which equation is true? A 2(b +5) = 6 2(b-4)= 12 B C 2(b + 3) = 10 D 2(b-5) = 14​

Answer 1

a.) 2(b+5)=6

Explanation:

`b=-2\\\\a.)2(b+5)=6\\2[(-2)+5]=6\\2(3)=6\\6=6\\\\b.)2(b-4)=12\\2[(-2)-4]=12\\2(-6)=12\\-12\\eq 12\\\\c.)2(b+3)=10\\2[(-2)+3]=10\\2(1)=10\\2\\eq10\\\\d.)2(b-5)=14\\2[(-2)-5]=14\\2(-7)=14\\-14\\eq14`
