Answer:

The associative property of multiplication.

Step-by-step explanation:

We have been given an equation (7p)mn=7p(mn). We are asked to determine the property illustrated in the given equation.

We can see that in our given equation the associative property of multiplication is used.

The associative property of multiplication states that we can multiply numbers regardless of how they are grouped.

Therefore, associative property of multiplication is illustrated in the given equation.

I believe it is the associative property.

Check the picture attached.

Let m(BAE)=m(ACD)=α

(BAE and ACD are congruent, since they are alternate interior angles, or Z angles)

Let m(ABE)=β. 

So in triangle ABE, the measures of the angles are 90, α and β degrees.

This means that m(BCE)=β, since the 2 other angles of triangle BCE are 90 and α degrees.

thus, we have the similarity of triangles ABE and BCE,

so the following rations are equal:

\frac{AB}{BC} = \frac{BE}{CE} = \frac{AE}{BE}

so


\frac{AB}{BC} = \frac{x}{5} = \frac{8}{x}

so 

\frac{x}{5} = \frac{8}{x}

x^{2} =40

x= \sqrt{40}= \sqrt{4*10}=2 \sqrt{10}   (inches)


Remark, we can also apply Euclid's theorem directly.

Answer:

<h2>137°</h2>

Step-by-step explanation:

The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.

If m∠RST = 108°, then m∠STY = 108°.

We have the equation:

m∠UTY + m∠STY + m∠STU = 360°.

Substitute m∠STY = 108° and m∠UTY = 115°.

115° + 108° + m∠STU = 360°

223° + m∠STU = 360°          <em>subtract 223° from both sides</em>

m∠STU = 137°

The glee club is having their annual Spring performance. The equation 5a+2s=48 represents the money collected on the first night
V125BC [204]
First, put them directly above each other.
5a+2s=48
3a+2s=32

You need to combine these, but in order to do so, we want to get rid of one of the letters. The S's line up very well, and all we need to do is multiply the bottom equation by a negative 1. This will look like this,
-3a-2s=-32                        (and add it to the other equation)
5a+2s=48
                         This gives you
2a=16
Divide both sides by 2 to get a by itself.

a=8, is your answer!

If it asked for s, you would put 8 into whichever equation seems easier for you, and then its just simple crunching it out.

Hope this helped!
