Answer:
-6-2x
Step-by-step explanation:
Expand:
(x+3)2 = 2x+6
-4(x+3) = -4x-12
2x+6-4x-12 = -6-2x
The coefficient of n-9 is 1 because is the number in front of the variable n
55% of 1800 = 0.55(1800) = 990...so there are 990 girls in the school
30% of 990 = 0.30(990) = 297...so there are 297 girls who take the bus
