Answer: $2061.55\ m$

Step-by-step explanation:

Given

The two communication mask are 2 km apart

Ubi's home is 500 m east of one of the mask

Suppose its distance from the other's is x

From the figure, we can write

$\Rightarrow x^2=2000^2+500^2\\\Rightarrow x^2=4\times 10^6+25\times 10^4\\\Rightarrow x=2061.55\ m\ \text{or}\ 2.061\ km$

What is (x+4)(3x+7)/(x+4)(x+2) simplified?

iren2701 [21]

Answer:

$\frac{3x+7}{x+2}$

Step-by-step explanation:

Given the following question:

$\frac{(x+4)(3x+7)}{(x+4)(x+2) }$

In order to simplify the expression given we can only cancel the common factor which is four.

$\frac{(x+4)(3x+7)}{(x+4)(x+2) }$
$cf=(x+4)$
$\frac{x+4}{x+4}$
$=\frac{3x+7}{x+2}$

Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."

Hope this helps.
