Which of the following choices is an equivalent expression for 12(r + t) - 6(r + t) + 4(r + t) - 2(r + t) A

8(r - t)

B

8(r + t)

C

8r + 7t

B  8(r + t)

Step-by-step explanation:

We must evaluate the equation in order to get the answer

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

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

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

8(r + t)

The answer is B

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
