15/9 =25/9x<br><br> I simplified it as much as I could but i'm stuck here:/
kvv77 [185]

Answer:

Step-by-step explanation:

We move all terms to the left: 15/9-(25/9x)=0 Domain of the equation: 9x)!=0 x!=0/1 x!=0 x∈R

We add all the numbers together, and all the variables

-(+25/9x)+15/9=0

We get rid of parentheses

-25/9x+15/9=0

We calculate fractions

=0 x=0/1 x=0

i hope helps you and if you want you can give me a brainly crown only if you want

faltersainse [42]

Answer:

x = - 12, 3

Step-by-step explanation:

By tangent secant theorem:

x(x + 9) =  {6}^{2}  \\  \\  {x}^{2}  + 9x = 36 \\  \\  {x}^{2}  + 9x - 36 = 0 \\  \\  {x}^{2}  + 12x - 3x - 36 = 0 \\  \\ x(x + 12) - 3(x + 12) = 0 \\  \\ (x + 12)(x - 3) = 0 \\  \\ x + 12 = 0, \:  \: x - 3 = 0 \\  \\ x =  - 12, \:  \: x = 3 \\  \\
