When the reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller, the

yawa3891 [41]

Answer: No solution

<u>Step-by-step explanation:</u>

1st number: x

2nd number: x + 2

reciprocal of the larger is $\frac{1}{x+2}$

4 times the reciprocal of the smaller is 4 $(\frac{1}{x})$

reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller is 4 $(\frac{1}{x})$ - $\frac{1}{x+2}$

the result is 56: 4 $(\frac{1}{x})$ - $\frac{1}{x+2}$ = 56

Solve the equation:

4 $(\frac{1}{x})$ - $\frac{1}{x+2}$ = 56

$\frac{4(x(x + 2))}{x}$ - $\frac{1(x(x + 2))}{x+2}$ = 56(x(x + 2))

4x + 8 - x = 56x² + 112x

3x + 8 = 56x² + 112x

0 = 56x² + 109x - 8

Use the quadratic formula to solve:

x = $\frac{-109+/-11\sqrt{113}}{112}$

The result is NOT AN INTEGER so there is NO SOLUTION

Step-by-step explanation:

n1 = n + 5

ns^2 = 3 + 3nb

6^2 = 3 + 3(11)

36 = 3 + 33
