Answer:
12y +16yi
Step-by-step explanation:
The thing about complex numbers is that you can treat them as binomials and use all of the things you know about multiplying and factoring polynomials.
Here, we assume you have ...
(5 +2yi)(4 -3i) -(5 -2yi)(4 -3i)
The factor (4 -3i) can be factored out, so you have ...
= ((5 +2yi) -(5 -2yi))(4 -3i)
= (4yi)(4 -3i)
= 16yi -12yi²
At this point, the definition of i comes into play, and you replace i² with -1.
= 12y +16yi
Answer:
Total cost =28.575
Step-by-step explanation:
wev are given
total Food cost=$22.50
cameron gave 9% meal tax of his total meal price
total meal price without tax is $22.50
9% of $22.50 will be
9% meal tax=22.50*9/100=2.025
he gave 18% tip of his total food cost without tax that is $22.50
18% of $22.50 will be
18% tip=22.50*18/100=4.05
for total meal cost we will add all costs and total cost will become
Total cost =22.50+2.025+4.05 =28.575
Answer=28.575
Answer:
<h2>18x + 30</h2>
Step-by-step explanation:
The distributive property: a(b + c) = ab + ac.
-6(-3x - 5) = (-6)(-3x) + (-6)(-5) = 18x + 30
Answer:
