4x + 8 = \frac{2}{3}(9 + x)

12x + 24 = 2(9 + x)             <em>multiplied both sides by 3</em>

12x + 24 = 18 + 2x             <em>distributed 2 on the right side</em>

10x + 24 = 18                      <em>subtracted 2x from both sides</em>

         10x = -6                     <em>subtracted 24 from both sides</em>

         \frac{10x}{10} = \frac{-6}{10}           <em>divided both sides by 10</em>

           x = \frac{-3}{5}

Answer: \frac{-3}{5}

use the guide to construct a two column proof proving △aec≅△deb, given that ca is parallel to db and e is the midpoint of ad. gi
MrMuchimi

By using the AAA congruence property of Triangles, △aec≅△deb is proved

It is given two triangles, Δaec and Δdeb, where e is the common point known as the midpoint of ad

Also, it is given that,

ca ║db

We need to prove that, △aec≅△deb

Then we'll use AAA congruence property of Triangles to prove the situation

As ca ║db

then, ∠cae = ∠ebd  (Alternate angles)

∠ace = ∠edb (Alternate angles)

and ∠aec = ∠deb (common angles)

Thus, by AAA congruence property, △aec≅△deb

Hence, proved

Find the arc length of the semicircle.
S_A_V [24]

Answer:

9π, or 28.26

Step-by-step explanation:

The Arc of the semicircle is the circumference of half a circle.

The radius of the semicircle is 9, and the circumference of a circle is 2πr, so it is 2π9 = 18π. since this is a semicircle, it is half of that, so 9π, or 28.26, since π is 3.14 here

Anybody know the answer?
leonid [27]

Answer:

The answer to your question is AD = 74

Step-by-step explanation:

Data

AB = CD = 10

BC = DE = 54

DE = 54

CD = 10

Process

From the picture we know that

      AD = AB + BC + CD

Substitution

      AD = 10 + 54 + 10

Simplification and result

       AD = 74
