$1.5 n^{2} + 7 = 20$

Short Answer

Expert verified

$n = 2.94$

Step by step solution

Step 1. Given Information.

The given equation is $1.5 n^{2} + 7 = 20$ .

Step 2. Calculation.

The solution of the given equation will be

$\begin{matrix} 1.5 n^{2} + 7 = 20 \\ 1.5 n^{2} = 20 - 7 \\ 1.5 n^{2} = 13 \\ n^{2} = \frac{13}{1.5} \end{matrix}$

Simplify it further.

$\begin{matrix} n = \sqrt{8.667} \\ = 2.943 \\ n \approx 2.94 \end{matrix}$

Step 3. Conclusion.

The solution of the given equation is $n = 2.94$ .
