Answer:

\frac{x^2-4x-21}{(x+3)(x-4)}

Step-by-step explanation:

R(x)=(\frac{x+1}{x+3})-(\frac{x+17}{x^(2)-x-12})

R(x)=(\frac{x+1}{x+3})-(\frac{x+17}{(x+3)(x-4)})

R(x)=\frac{(x+1)(x-4)}{(x+3)(x-4)} - \frac{x+17}{(x+3)(x-4)}

R(x)= \frac{x^2-3x-4-x-17}{(x+3)(x-4)}

R(x)=\frac{x^2-4x-21}{(x+3)(x-4)}

erastova [34]

Answer: 3432.56

Step-by-step explanation: Everything is on the attached file, enjoy!!! If you have any further questions, just ask me, I'd be glad to help!

Alert: IDK if it is attached, so sorry if it isn't i'll try to explain it.

2490.05 is the initial value how much leo started with.

2.5% + 100% = 1.025

weekly =13weeks

multiply 1.025 by the sqrt of 13 since that's the amount of weeks.

that gets you 3432.56.
