Answer:
55 +48i
Step-by-step explanation:
Complex numbers can be treated as though they were binomials with a variable "i". At the end, any instance of i² can be replaced by -1.
(8 +3i)² = 8² + 2(8)(3i) +(3i)² = 64 +48i -9
= 55 +48i
Answer:
I think the answer is 8
Step-by-step explanation:
2x+8=3kx (3k-2)x+8=0
3x-kx=2. (3-k)x-2=0
3k-2)x+10=3-k)x
4k-5=10/x
///////
3x-y-2=2x+8-3y
X+2y-10=0
X+2kx-10=0
K=(10-x)/2x
Answer:
16%
Step-by-step explanation:
percent = part/whole × 100%
percent = 7440/46500 × 100%
percent = 0.16 × 100%
percent = 16%
The current sale price would be $123.60.
20% of $618 is 123.6. So turn that into dollars and cents and you get $123.60
