Answer and Step-by-step explanation:

Since we have given that

$2x-4y=18\\\\3x+3y=0$

We need to mention the properties for the given steps:

$6x-12=54\\\\6x+6y=0$

1) Multiplication property of equality

$-18y=54$

2) Addition property of equality

$y=-3$

3) Division property of equality

$2x-4(-3)=18$

4) Substitution property of equality

2x+12=18

5) Simplify

2x=6

6) Subtraction property of equality

x=3

7) Division property of equality

A (103)(109)

=103*109

=(10*10*10)*(10*10*10*10*10*10*10*10*10)

=10*10*10*10*10*10*10*10*10*10*10*10

=1012

Limx→+∞ (x-(lnx)^2) =?

expeople1 [14]

$\lim_{x\to\infty}(x-\ln(x)^2) \\\lim_{x\to\infty}(x-2\ln(x)) \\\lim_{x\to\infty}\Big(x\Big(1-\dfrac{2\ln(x)}{x}\Big)\Big) \\\lim_{x\to\infty}x\cdot\lim_{x\to\infty}\Big(1-\dfrac{2\ln(x)}{x}\Big) \\\infty\cdot\Big(\lim_{x\to\infty}(1)-\lim_{x\to\infty}\Big(\dfrac{2\ln(x)}{x}\Big)\Big) \\\infty\cdot(1-2\lim_{x\to\infty}(1/x)) \\\infty\cdot(1-0) \\\infty\cdot1=\boxed{\infty}$
