He can make 15 chess boards.
All you need to do is multiply 3 by 5.
For this case we have the following equation:
x ^ 2 + 18x + 32 = 0
Rewriting we have:
x ^ 2 + 18x = -32
By completing squares we have:
x ^ 2 + 18x + (18/2) ^ 2 = -32 + (18/2) ^ 2
Rewriting:
x ^ 2 + 18x + (9) ^ 2 = -32 + (9) ^ 2
x ^ 2 + 18x + 81 = -32 + 81
x ^ 2 + 18x + 81 = 49
(x + 9) ^ 2 = 49
Answer:
(x + 9) ^ 2 = 49

Answer:
<h2><em><u>
.1etc</u></em></h2>
Step-by-step explanation:
It would be 16 divided by 3 and from the answer you get from that you should divide it by itself equaling infinite .111111111111etc
Answer with Step-by-step explanation:
For any complex number x+iy the polar form is represented as
where
Part a) x+iy = -1+i
Thus 
Thus using De-Morvier's theorem
Part 2) x+iy = 1+3i
Thus 
Thus using De-Morvier's theorem
