HCF= highest common factor
LCM= least common multiple
It would be called an ecological model.
<span>( 9 + 5i)( 9 + 8i)
= 9(9+8i)+5i(9+8i)
= 81+72i+45i+40i^2
= 81+117i+40(-1)
= 81-40+117i
= 41+117i. Answer</span>
The answer is (-4, 5) x= -4 y= 5
There is no answer as this isn't an equation. And moreover it's in its simplest form.
