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
Whats the equation...............
you would add 4x-3 to 6x-6 and equal it to 180° which is 6x+4x-6-3=180° which is 10x-9=180° then use inverse operation to solve it.
