Answer:
z = -9.538546756+ 15.26486573i
Step-by-step explanation:
z = |z| cos theta + |z| i sin theta
We know |z| and theta
z = 18 cos 122 +18i sin 122
z = -9.538546756+ 15.26486573i
18(3+14) x 6(21+4) is an example I just came up with you distribute the 18 to the 3 and the 4. And distribute the 6 to 21 and 4.
The cheaper price among this set of orange sales is the one done by trader B, who sells <u>8 for N120</u>.

What would make finding the answer a bit easier, is converting them into improper fractions. You would turn that first fraction to

and the second fraction to

. (You are dividing a negative by a negative, therefore, your answer would be a positive.
Let's follow the procedure of keeping, switching, and flipping. You keep the first improper fraction, switch the division sign to a multiplication sign, and flip the second fraction. That would make it :

×

.
You multiply the 9 and the 2, you get 18. You multiply the 3 and the 4, you get 12. That makes it

. This, converted to a mixed fraction, makes 1

., which is the same as 1

. Your answer is the
SECOND CHOICE.
