Answer:
Step-by-step explanation:
P = 4 + 6 + (3y - 2) Remove the brackets
P = 10 + 3y - 2 Combine
P = 8 + 3y
Note 3y must be less than 8. That's because 2 sides of any triangle must be larger than the 3rd side or else you don't have a triangle.
Answer:
Step-by-step explanation:
By definition scientific notation has the following form:
Where a is a number between 1 and 10 but not including 10, and the exponent b is an integer.
The decimal point must be after the first digit.
Therefore, keeping the information above on mind, you can write the number as following:
The property x^axb makes it x^a+b so x^5x-2 ,
Therefore x^-10 is final
