Answer:
D
Step-by-step explanation:
It's not similar because when aligning the values they don't match. 3 × 5 = 15 so that bottom line matches but when you do the same thing to the other line: 5 × 3 does not equal 9. There is no similarity between the two triangles.
This can be modeled by the equation f(x)=7+5x
Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22
If x=50 then f(50)=7+5(50)
f(50)=$257
