What did this person do wrong? Honestly really stuck and do not remember geometry!
dmitriy555 [2]

Answer:

See below.

Step-by-step explanation:

Using the right triangle altitude theorem, the correct proportions are:

\dfrac{AB}{AC} = \dfrac{AC}{AD}

\dfrac{AB}{x} = \dfrac{x}{AD}

\dfrac{25}{x} = \dfrac{x}{16}

x^2 = 25 \times 16

x = 20

AC = 20 cm

\dfrac{AB}{CB} = \dfrac{CB}{DB}

\dfrac{AB}{y} = \dfrac{y}{DB}

\dfrac{25}{y} = \dfrac{y}{9}

y^2 = 25 \times 9

y = 15

CB = 15 cm

Solve y+2x=5;x=-1,0,3
Anni [7]
If x=-1 => y-2=5=> y=7,x=-1
If x=0=> y+0=5=> y=5,x=0
If x=3=> y+6=5=> y=-1,x=3
