Hi there!

Your question is mistaken. You must have meant to ask for the value of x.

By definition of a parallelogram, we know that there must be two pairs of parallel sides. We also know that a parallelogram will follow this form:

<em>See attachment.</em>

<em />

Therefore, we know that 6x-15=x+15. Let's solve:

6x-15=x+15

5x-15=15 <em>Subtract x from both sides.</em>

5x=30 <em>Add 15 to both sides. Now the variable is isolated.</em>

x=6 <em>Divide both sides by 5.</em>

<em />

So as you can see, x = 6. If you tried to solve this and got a negative solution, remember that lengths and distances can never be negative (e.g. I can't go -5 miles; a square can't have a length of -3 feet, etc.).

Hope this helps! :^)

Answer:

x=6

Step-by-step explanation:since the opposite triangles are congruent, they are equal. so 6x-15=x+15. Then i cancelled the negative 15 on the the left by adding 15. So i was left with 6x=x+30. Then you subtract the x on the right from the 6 x and you are left with 5x=30. 30 divided by 5 is 6. X=6

salantis [7]

Answer:

No.P=347

Step-by-step explanation:

The fence is 2768 feet long, how many posts should be placed along the fence if the adjacent distance between them is 8 feet?

How to start and end with a post the number of them (No.P) will always be the distance of the fence (f) between the adjacent distance of the posts (p) plus one     No.P = \frac{f}{p}+1= \frac{2768}{8}+1 = 346+1=347

As an example we have graph 1

Solve the following equation for h.<br> r+3Q/h=t
Arada [10]

Answer:

             \bold{h=\dfrac{3Q}{t-r}}

Step-by-step explanation:

\bold{r+\frac{3Q}h=t}\\-r\qquad\ -r\\\bold{\frac{3Q}h=t-r}\\\cdot h\qquad \cdot h\\ \bold{3Q=(t-r)h}\\^{\div(t-r)\quad\div(t-r)}\\\bold{\dfrac{3Q}{t-r}=h}

Or, if you mean (r+3Q)/h=t:

\bold{\frac{r+3Q}h=t}\\{}\ \ \cdot h\quad\ \cdot h\\\bold{r+3Q=ht}\\{}\ \ \div t\qquad \div t\\\bold{\dfrac{r+3Q}{t}=h}\\\\\bold{h=\dfrac{r+3Q}{t}}
