Answer:
21+12i i hope this will help you
Step-by-step explanation:
(3-4i)(1+5i)-(2-i)
=[3(1+5i)-4i(1+5i)]-(2-i)
=[3+15i-4i-20i²]-(2-i)
=(3+11i-20i²)-(2-i)
opening brackeys
=3+11i-20i²-2+i
=3+11i+1i-20i²-2
as we know that i²=-1
=3-20(-1)-2+12i
=3+20-2+12i
=21+12i

Answer:
0.78125 pounds
Step-by-step explanation:
the weight of 8 brick is 6.25 pound
divide the weight by 8 to take the weight for the one brick
Lets list what we know:
1.5 cups = 18 cookies
How many cups in 1 cookie will help us find the answer:
1.5 / 18 (1.5 cups per 18 cookies)
divide both sides by 1.5 (to get how many cookies in 1 cup)
1 / 12 (1 cup = 12 cookies)
Now, how many times does 12 fit in 30?
30/12 = 2.5
This means it takes 2 and a half cups of raisins to get 30 cookies.
