Question

These are triangle inside of triangles proportions can you help me with this ?

Answer 1

Note that:

`x+23=2\mleft(2x+25\mright)`

Applying the distributive property, this is equivalent to:

`x+23=4x+50`

now, putting the like terms together we obtain:

`4x-x=\text{ 23-50}`

this is equivalent to:

`3x\text{ = -27}`

solving for x, we get:

`x\text{ = -}(27)/(3)=-9`

so that, we can conclude that the correct answer is:

`-9`
