Answer:

Step-by-step explanation:

Since they are similar triangles, we can use proportions

5 10

------ = -------------

5+7 10+?

5 10

------ = -------------

12 10+?

Using cross products

5( 10+?) = 12*10

Divide each side by 5

10+? = 12*10/5

10+? = 24

Subtract 10 from each side

10+?-10 = 24-10

? = 14

A^3b^-2c^-1d if a=2 b=4 c=10 d=15 express as a reduced fraction

I am Lyosha [343]

$\bf a^3b^{-2}c^{-1}d\implies \cfrac{a^3d}{b^2c}\qquad \begin{cases} a=2\\ b=4\\ c=10\\ d=15 \end{cases}\implies \cfrac{2^3\cdot 15}{4^2\cdot 10}\implies \cfrac{120}{160}\implies \cfrac{3}{4}$
