Question

${9x}^{2} + {25x}^{2} = 181$

Answer 1

$9 {x}^{2} + 25 {x}^{2} = 181 \\ 34 {x}^{2} = 181 \\ {x}^{2} = \frac{181}{34} \\ x = \sqrt{ \frac{181}{34} } \\ x = 2.307$

Answer 2

Hey dear!


here is yr answer.......

9x² + 25x² = 181

(3x)² + (5x)² = 181

8x² = 181

x² = 181/8

x² = 22.625

x = √22.625

x = 4.75


Hope it hlpzzz......
