Answer:
x(6 + 8x²) or 6x + 8x³.
Step-by-step explanation:
"The square of x" can be represented by x² and 8 times that would be 8 * x² or 8x². The sum of 6 and 8x² can be represented by 6 + x² and the product of x and 6 + x² can be represented by x * (6 + 8x²) or x(6 + 8x²) which simplifies to 6x + 8x³.
Total of ratio 5+7=12
60/12 = 5
For boys 5x5 = 25 boys in her class
(For girls 7x5 = 35)
The range is 30 to find the range u subtract the biggest from the smallest so 81-51=30 hope this helps
