Question

Daca a^2-b^2=24 si a-b=2√2,aflati a+b
COROANA!!!!!

Answer 1

${a}^{2} - {b}^{2} = 24$

$(a - b)(a + b) = 24$

$2 \sqrt{2} (a + b) = 24$

$a + b = \frac{24}{2 \sqrt{2} }$

$a + b = \frac{24 \sqrt{2} }{2 \sqrt{2} \times \sqrt{2} }$

$a + b = \frac{24 \sqrt{2} }{2 \times 2}$

$a + b = \frac{24 \sqrt{2} }{4}$

$a + b = 6 \sqrt{2}$
