help me please if you can please explain me how to do it

Step-by-step explanation:
Ok you would need to do x*y-99.08/[tex]\left \{ {{y=2} \atop {x=2}} \right.[/tex][tex]\alpha \geq \leq \left \{ {{y=2} \atop {x=2}} \right. \int\limits^a_b {x} \, dx \int\limits^a_b {x} \, dx \lim_{n \to \infty} a_n[/tex]²[tex]\neq \neq \pi \frac{x}{y} \alpha \beta x^{2} x^{2}[/tex] and that should be your answer. 5 is your answer :)
