The length of VX equals to 80
Below I show my work of how I found the missing length.

To find the missing length, you pick the starting location. Then go in any direction and then do the same to the other side. Then write a ratio.

I decided to start at 46 and then go downward.

46/23=x/17

Then you cross multiply

43*17=x*23

782=23x

Divide 23 on both sides

X=34.

Then add 34 by 46 to get the length of VX.

Below is a picture of notes on how to solve these types of problems.

Which expression is equivalent to -1/4 x + 1/2?

Anna71 [15]

The expression is given by:

$-\frac{1}{4}x+ \frac{1}{2}$

So we need to find an equivalent equation for this problem. Then, we will apply some mathematical rules:

Extracting the common factor 1/4, then:

$\frac{1}{4}(-x+2})$

Or extracting the common factor -1/4, then:

$-\frac{1}{4}(x-2})$

So, comparing these solutions with the answers about, there is no any answer that matches.

It is approximately -.4048

H=10^(-pH)

log H = -pH

pH=-logH => so it is affirmed that it is -.40
