Answer:

Please check the explanation.

Explanation:

Given the expression


2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2

solving the expression


2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2

as


  • 2\left(P+1\right)+3\left(P+2\right)=5P+8

so the expression becomes


5P+8>2

subtracting 8 from both sides


5P+8-8>2-8


5P>-6

Dividing both sides by 5


(5P)/(5)>(-6)/(5)


P>-(6)/(5)

Therefore,


2\left(P+1\right)+3\left(P+2\right)>2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:P>-(6)/(5)\:\\ \:\mathrm{Decimal:}&\:P>-1.2\\ \:\mathrm{Interval\:Notation:}&\:\left(-(6)/(5),\:\infty \:\right)\end{bmatrix}

The graph is also attached below.
