Match each expression in column A with an equivalent expression from column B. Column A

12r + t − 4r + 6t
(12r + 2t) − (4r + 10t)
12(r + t) − 6(r + t) + 4(r + t) − 2(r + t)

Column B

8(r − t)
8(r + t)
8r + 7t

12r + t − 4r + 6t

see answers below to match them

Step-by-step explanation:

12r + t - 4r + 6t

=12r - 4r + t + 6t

=8r + 7t

(12r+2t) - (4r+10t)

=12r + 2t - 4r - 10t

=8r - 8t

=8(r-t)

12(r+t)-6(r+t)+4(r+t)-2(r+t)

=(12-6+4-2)(r+t)

=8(r+t)

b.an increase in a causes b to decrease

25/6 hope it : )
