Rachael made 64 ounces of potato salad
Treat "13 4/5 feet below sea level" as a negative quantity. Then add the increase, "1542 feet," obtaining
(1542 - 13 4/5) feet = 1528 1/5 feet above sea level.
Start by expanding the first two brackets
(2+i)(3-i)
Multiply 2x3=6, then 2x I = 2i, then i x 3= 3i, then i x i= i2( i squared)
so it will be written as 6+2i+3i+i2( squared)
from here you can see that 2i and 3i can be added together to make 5i
so, 6+5i+i2(squared)
Then you bring in the third bracket from the question.
(6+5i+i2)(3+i)
6 x 3=18
6 x i= 6i
5i x 3=15i
5i x i=5i2(squared)
2x3=6
2x i= 2i
so you get 18+6i+15i+5i2(squared)+6+21
6i and 15i can be added together
18, 6 and 21 can be added together
so, 21i+5i2(squared)+45
Answer:
it is b
Step-by-step explanation:
because it will follow the same direction it came from the begining.
Yea you multiply it 1 plus 2 times 9 and get 52
