Another way to estimate sqrt(18) is to understand that

sqrt(18)

=sqrt(9)sqrt(2)

=3sqrt(2)

=3*1.414

=4.242

Note: estimate for sqrt(2) can be by common usage, or the fact that 14*14=196.

memorizing a few square-roots is an advantage in these situations:

sqrt(2)=1.41421356

sqrt(3)=1.7320508

sqrt(5)=2.2360680

etc.

Answer:

$\dfrac{5x + 1}{6(x - 2)}$

$\dfrac{5x + 1}{6x - 12}$

Step-by-step explanation:

Fatorizam-se os denominadores.

2x - 4 = 2(x - 2)

3x - 6 = 3(x - 2)

O minimo multiplo comum dos denominadores e

2(3)(x - 2)

$\dfrac{x + 1}{2x - 4} + \dfrac{x - 1}{3x - 6} =$

$= \dfrac{3(x + 1)}{2(3)(x - 2)} + \dfrac{2(x - 1)}{2(3)(x - 2)}$

$= \dfrac{3(x + 1) + 2(x - 1)}{6(x - 2)}$

$= \dfrac{3x + 3 + 2x - 2)}{6(x - 2)}$

$= \dfrac{5x + 1}{6(x - 2)}$

$= \dfrac{5x + 1}{6x - 12}$

Lily is a lilypad in a small pond. Lily doubles in size each day. On the 20th day she covers the whole pond. On what day was Lil

svetoff [14.1K]

Answer:

19th day

Step-by-step explanation:

So say Lily was 1 when Lily was planted

First day Lily is 2

Second day Lily is 4

Third day Lily is 8

etc...

See the pattern?

The pattern is 2^x

On the 20th day, Lily was 2^20

So when Lily was half, Lily was 2^20 / 2

2^x = 2^20 / 2

2^x = 2^19

On the 19th day, Lily was half.
