Hello there!
Scientific notation is when the number is between 0 and 10 times 10 to a power.
In this case we'd get 2.4 x

.
Hope This Helps You!Good Luck :)
P = [60] cm
Explanation:
6.5 cm + 6.5 cm + 7.5 cm + 7.5 cm + 7.5 cm + 7.5 cm + 8.5 cm + 8.5 cm
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
Written as a unit rate would be 5 dollars for each pounds.
I hope this helps!
