Determine if the pairs of expressions below are always equivalent. Prove your answer A. 4n + 12 and 4 (n +3)

B. m + m 3m and 3m + 2

C. 4x + 8y and 4 (x + 8y)

D. 3 (2t + 2 ) and ( t + 1 ) x 6

E. p + p and p + 7

​

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
