Lisa is incorrect although it is an odd number it is not composite. It only has itself and 1. Therefore its a prime number.
This is the definition for prime if you still dont understand.
A prime number is a whole number greater than 1 whose only factors are 1 and itself.

Step-by-step explanation:
1. (4x+5y)(2x-3y)+3xy= 4x*2x-4x*3y+5y*2x-5y*3y+3xy=8x^2-12xy+10xy-15y^2+3xy= 8x^2+xy-15y^2
2. (2x^2+3)(4x+5)-8x(x^2-2)=2x^2*4x+2x^2*5+3*4x+3*5-8x*x^2+8x*2=
=8x^3+10x^2+12x+15-8x^3+16x=
=10x^2+28x+15
