Answer:
x²+17x+66
Step-by-step explanation:
Step 1: x×(x+6)+11(x+6)
Step 2: x²+6x+11(x+6)
Step 3: x²+6x+11x+66
Answer: x²+17x66
Answer:
2.5 minutes
Step-by-step explanation:
Dividing the average speed by distance will give you 2.5 which is the average speed the hoverboard goes assuming the hoverboard will travel at the same speed the answer is 2.5 minutes.
Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.
Let, 3x is number of children.
So, 6x is number of adults and 8x is number of pensioners.
Now,
3x + 6x + 8x = 85
17x = 85
x = 5
Therefore, number of pensioners are 8×5 = 40.
Hence, this is the required solution.
