Question

Simplify 9 (2a + 3b - 4c) + 10 (a + 2b + 3c)​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

Given

9 (2a + 3b - 4c) + 10 (a + 2b + 3c)

Solution

18a + 27b - 36c + 10a + 20b + 30c

18a + 10a + 27b + 20b + 30c - 36c

28a + 47b - 6c

Answer 2

Answer:

28a + 47b - 6c

Step-by-step explanation:

9 (2a + 3b - 4c) + 10 (a + 2b + 3c)​

= $[(9*2a)+(9*3b)-(9*4c)] + [(10*a)+(10*2b)+(10*3c)]$

= $[18a+27b-36c]+[10a+20b+30c]$

= $(18a+10a) + (27b+20b) + (-36c + 30c)$  

= 28a + 47b + (-6c)

28a + 47b - 6c
