I = PRT
I\PR = T

I just divided both sides by PR.

Answer:

[tex]2a^2+2a-11[/tex]

Step-by-step explanation:

Given,

[tex]C = 2a^2 - 5------(1)[/tex]

[tex]D=3 - a-------(2)[/tex]

Thus,  

[tex]C-2D = 2a^2 - 5-2(3 - a)[/tex]  ( From equation (1) and (2) )

[tex]=2a^2 - 5 - 6 + 2a[/tex]            ( By distribution property )

[tex]=2a^2+2a-11[/tex]                      ( Combined constant )

Hence, C - 2D is equal to [tex]2a^2+2a-11[/tex]
