Answer:

x = 30/7

Step-by-step explanation:

−2(x+13)+9x=4

Multiply out the bracket

-2x - 26 + 9x = 4

Combine the x terms

(-2x + 9x) - 26 = 4

7x - 26 = 4

Rearrange into the form Ax = b, so all the x's are on one side and the integers are on the other.

7x = 4 + 26

7x = 30

Rearrange into the form x = b, so x is on one side and the integer is on the other.

x = 30/7

Since BC is parallel to DE, triangles ABC and ADE are similar. What are the lengths of the unknown sides?
Yuri [45]

Answer:

Option D. AC= 10 cm and CE= 5 cm

Step-by-step explanation:

From the given figure two triangles ΔABC and ΔADE are similar and two lines BC║DE.

From these similar triangles we know

\frac{AB}{AD}=\frac{BC}{DE}=\frac{AC}{AE}

\frac{8}{12}=\frac{BC}{9}=\frac{AC}{AE}

Therefore \frac{AC}{AE}=\frac{8}{12}=\frac{2}{3}

Or AC=\frac{2}{3}AE

Now from pythagoras theorem

AE = √(AD²+ED²) = √(12²+9²) = √(144+81) =√225 = 15 cm

Since we know side AC = \frac{2}{3}AE

                                        = \frac{2}{3}\times 15

                                        = 10 cm

Therefore AC = 10 cm and AE = 15cm and CE = (15-10) = 5 cm
