Hello there,
Okay, Let's start with RS. So what I did was I subtracted (3x-4)-(4x+1) and the reason I did that was because (4x+1) equal's the whole length. And sense I dont know the length of RS yet. . . I will use the other length to find out. So when you calculate those both. Your correct answer is (x+5).
RS= x=5
Hope this helps.

Answer:
x² + 16x + 64
Step-by-step explanation:
To find f(g(x)) , substitute x = g(x) into f(x), that is
f(x + 7)
= (x + 7)² + 2(x + 7) + 1 ← expand (x + 7)² using FOIL
= x² + 14x + 49 + 2x + 14 + 1 ← collect like terms
= x² + 16x + 64
The answer is 180 if right
Because u have to focus on that last number if the last number is greater or less thats the answer
