Question i:
If \( \frac{x}{3} = \frac{y}{5} = \frac{z}{4} \), what is \( \frac{x+z+y}{x} \) equal to?
- 1. 3
- 2. 4
- 3. 6
- 4. 2
Question j:
Solve: \[ \frac{(7x+5)^2 + (7x-5)^2}{(7x+5)^2 + (7x-5)^2} = \frac{25}{24} \]
- 1. \( \frac{23}{21} \)
- 2. \( \frac{20}{21} \)
- 3. \( \frac{15}{29} \)
- 4. \( \frac{21}{28} \)
