Answer:

$\boxed{\bold{15x+78}}$

Step By Step Explanation:

Apply Rule - (-a) = a

$\bold{6\left(4x+12\right)-9x-18+4\cdot \:6}$

Multiply: 4 · 6 = 24

$\bold{6\left(4x+12\right)-9x-18+24}$

Expand $\bold{6\left(4x+12\right): \ 24x+72}$

= $\bold{24x+72-9x-18+24}$

Simplify $\bold{24x+72-9x-18+24}$

= $\bold{15x+78}$

Step-by-step explanation:

Okay first set a comparison since the two triangles are similar

x-1/20=x-1+27/3x+8

x-1/20 = x+26/3x+8

cross multiply

20x+520=3x^2+8x-3x-8

3x^2-15x-528=0

3(x^2-5x-176)=0

im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid

x=16, x=-11

it has to be positive so x=16
