Rewrite each of the following expressions for concurrent processing, and then code each one. Assume that the system has four processors. Use the terms COBEGIN and COEND to delimit the sections of concurrent code. Identify which expressions, if any, might NOT run faster in a concurrent processing environment.

a. A`3*(B*(C+D) )
b. X*(Y*Z*W*R)
c. M*T*R

Python. primary u. s. interstate highways are numbered 1-99. odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. thus, the 405 services the 5, and the 290 services the 90. given a highway number, indicate whether it is a primary or auxiliary highway. if auxiliary, indicate what primary highway it serves. also indicate if the (primary) highway runs north/south or east/west.
