What is the solution of<br><br>log6x + log6(x + 5) = 2?

exis [7]

Answer:

Doesn't have solution.

Step-by-step explanation:

x ≠ 0; x > 0 (I)

x - 5 > 0

x > 5 (II)

$log_6 x + log_6 (x + 5) = 2 \\\ log_6 [x(x + 5)] = 2 \\\ x^2 + 5x = 36 \\\ x^2 + 5x - 36 = 0 \\\ \Delta = 5^2 - 4.1.(- 36) \\\ \Delta = 169 \\\ \sqrt{\Delta} = \pm 13 \\\ x' = \frac{- 5 + 13}{2} \\\\ x' = 4 \\\ x" = \frac{- 5 - 13}{2} \\\\ x" = - 9$

Then, this expression doesn't have solution.

I Hope I've helped you.

Answer:

$JK=2.25\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

so

$\frac{JK}{ST}=\frac{KL}{TU}$

substitute the given value and solve for JK

$\frac{JK}{1.5}=\frac{6}{4}$

$JK=(1.5)\frac{6}{4}$

$JK=2.25\ units$
