Step-by-step explanation:
-4y+8-3x+4y+9+5x
Combine like terms
-3x +5x -4y +4y +8+9
2x +0 +17
Y=.25x is the only resonable answer
Answer:
X=0 or x=8/5
Step-by-step explanation:
Answer:(a² - 4b² - 9)(a² - 4b² + 9)
(a^4 - 8a²b² + 16b^4) - 81
= [(a²)² - 2.4a²b² + (4b²)²] - 9²
= (a² - 4b²)² - 9²
= (a² - 4b² - 9)(a² - 4b² + 9)
