Matrix presentation of ode

$\left(\begin{array}{c}{x}_{1}^{\text{'}}\\ {x}_{2}^{\text{'}}\end{array}\right)=\left(\begin{array}{cc}4& 1\\ 1& 3\end{array}\right)\begin{array}{c}{x}_{1}\\ {x}_{2}\end{array}$

Is it possible to write this ode in one equation ? write if it is possible.

How am I supposed to know this ?

How am I supposed to find the solution to the non-homogeneous ode ?

$\overrightarrow{Y}\text{'}=\left(\begin{array}{cc}-4& 2\\ 2& -1\end{array}\right)\overrightarrow{Y}+\left(\begin{array}{c}{x}^{-1}\\ 2{x}^{-1}+4\end{array}\right)$

A flexible balloon contains 0.375 mol$\mathrm{m}\mathrm{o}\mathrm{l}$ of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7350 cm3$\mathrm{c}{\mathrm{m}}^{3}$ and a temperature of 22.0 ∘C${}^{\circ}\mathrm{C}$. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K${C}_{p}=33.26\phantom{\rule{thickmathspace}{0ex}}\mathrm{J}/\mathrm{m}\mathrm{o}\mathrm{l}\cdot \mathrm{K}$ and γ=4/3$\gamma =4/3$.

What is the total heat Q$Q\text{Q}$ supplied to the gas in the process?

**2. **If a quadrilateral is equiangular, then it is equilateral.

**3.** Every isosceles triangle has at least one line of symmetry.

**4.** Every equilateral triangle has exactly three lines of symmetry.

**5.** If two angles are not congruent, then the two angles are not right.
