1 answer:
7(3 - x) < 5x - 15
- Distribute 7 inside the parentheses.
21 - 7x < 5x - 15
- Subtract 21 from both sides.
-7x < 5x - 36
- Subtract 5x from both sides.
-12x < -36
- Divide both sides by -12. The equality sign will get flipped because you are dividing by a negative.
x > 3

<h3>Solution</h3>
<u>Substitute ar in the second equation</u>
- ar⁵= 16
- 4r⁴ = 16
- r⁴ = 4
- r = √2
<u>Then finding a₄</u>
- a₄ = a₂*r² = 4*(√2)² = 4*2= 8
