Find the value of x.<br> 7<br> Х<br> 3<br> Z<br> X =√[?]<br><br> Pls help explain !!
Alisiya [41]

Answer:

Answer:

 x = √70

Step-by-step explanation:

The triangles shown are all similar, so the corresponding sides are proportional.

 hypotenuse/long side = x/7 = (7+3)/x

Cross-multiplying gives ...

 x^2 = 7(10)

 x = √70

_____

You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.

A similar "geometric mean" relation holds for the short side:

 BC = √(CD·CA)

There is yet another "geometric mean" relation that holds for the altitude:

 BD = √(CD·AD)

Rosa has a goal of running a total of 100 miles this month. Each day that she ran, she 37 ran 5 miles. Which expression could Ro
enot [183]
Hi there!

In order to figure out how many miles Rosa has left to run, you should subtract the number of days she has ran (d) times the number of miles per day (5) from the total miles that she plans to run (100). The equation for this would be 100 - 5d, or answer choice A. 

Hope this helps!! :)
