Answer:
Let x = Kilometers by bus
then x + (x + 350) = 1100
2x = 750
x = 375 by bus
x - 350 + x = 1100
2x = 1450
x = 725 by train

Answer:
6x² + 12y² + 17xy - 25xz
Step-by-step explanation:
(2x + 3y) (3x + 4y - 5z)
= 6x² + 8xy - 10xz + 9xy + 12y² - 15yz
= 6x² + 12y² + 8xy + 9xy - 10xz- 15yz
= 6x² + 12y² + xy (8 + 9) - xz (10 + 15)
= 6x² + 12y² + 17xy - 25xz
