Answer:
35
Step-by-step explanation:
B -13 -34i
(7 + 2i)(-3 - 4i)
Take the 7 then times it buy the second bracket 7x(-3-4i) then take 2i from the first bracket and times it with the second bracket 2ix (-3-4i)
Then keep simplifying
Y and x are the two varibles so 5 and 10 are your contants
32 ounces is 2 pounds so simple math 3+2=5 si your answer is 5 pounds
