Given a ≠ ± b and (a^2-b^2) / (a+b)=12 find a-b.

grigory [225]

Answer:

$\sqrt{12a \: + \: 12b \: - \: 2ab \: + \: 2b {}^{2} }$

Step-by-step explanation:

(a²-b²) / (a+b) = 12

a² - b² = 12(a+b)

(a-b)² + 2ab - 2b² = 12a + 12b

(a-b)² = 12a + 12b - 2ab + 2b²

a - b =

$\sqrt{12a \: + 12b \: - 2ab \: + \: 2b {}^{2} }$

Ann and bill share an amount of money in ratio 7:n. Ann gets 28%of the money. workout value of n

poizon [28]

If they share the money in ratio 7:n

And Ann had 28%

Thus unit ratio will be 28/7 = 4

Since Bill had 100 - 28 = 72%

Bill ratio will be 72/4 = 18

7:n will be 7:18

Thus the value of n is 18
