Find the limit. use l'hospital's rule if appropriate. if there is a more elementary method, consider using it. lim x→4 x2 − 16 x

ivolga24 [154]

Probably you are supposed to compute

$\displaystyle\lim_{x\to4}\frac{x^2-16}{x^2-4x}$

Factorize the numerator and denominator, then simplify:

$\displaystyle\lim_{x\to4}\frac{(x-4)(x+4)}{x(x-4)}=\lim_{x\to4}\frac{x+4}x=\frac{4+4}4=2$

The difference of two positive numbers is 7 and the sum of their squares is 109. Find the numbers.

Ray Of Light [21]

Answer:

$Numbers\ are\ 58\ and\ 51.$

Step-by-step explanation:

The the numbers are $x\ and\ y$ .

Difference:

$Difference\ of\ numbers=7\\\\x-y=7....................eq(1)$

Sum:

$Sum\ of\ numbers=109\\\\x+y=109...........................eq(2)$

Solve $eq(1)$ and $eq(2)$ .

$eq(1)+eq(2)\\\\x-y+x+y=7+109\\\\2x=116\\\\x=58\\\\Now\ from\ equation\ 1\\\\x-y=7\\\\y=x-7\\\\y=58-7\\\\y=51$
