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:
-47
Step-by-step explanation:
Step 1: Factor GCF
-6(x² - 6x - 36) = 0
Step 2: Divide by -6 on both sides
x² - 6x - 36 = 0
Step 3: Isolate x's
x² - 6x = 36
Step 4: Complete the Square
x² - 6x + 9 = 36 + 9
(x - 3)² = 45
Step 5: Move everything to one side
(x - 3)² - 45 = 0
So, a = 1, b = -3, c = -45
1 - 3 - 45 = -47
Answer:
Step-by-step explanation:
Yes bill is correct because both numbers are easy to add without regrouping, since when each of the digit are added there won't be carried over. Also, I believe Bill should be able to do simple mathematics like 2+3, 3+5 and so on.
Then, he should be able to add 3 plus 0 in his head and keep the result as 3. And then add the other 2+4 and he will put the two result together as 63
(Hint: how are these angles related to one another?)
a.
40.5
c.
30
b.
16
d.
60
