There's this many Packages and this many cans in each package right? All you have to do is multiply the number of cans and the number of packages to get the total number of cans.
For the cost is the same thing. If you know the cost is this much, multiply the amount of packages×The cost of each package which will give you the total cost. Good luck
The perimeter of a certain polygon is the sum of the measures of all its sides. If we are to use this concept with the given polygon above then that would be,
P = (3x + 1) + x + x + ?
We are also given that the perimeter is equal to 6x + 2. We substitute this to the equation derived,
6x + 2 = (3x + 1) + x + x + ?
Simplifying,
6x + 2 = 5x + 1 + ?
? = x + 1
Answer: The last side is equal to x + 1.
It can be
scientific notation is defined as
(number greater than or equal to 1 and less than 10) times 10^x whre x is the number of places the decimal must be moved to the right to return it to the original value (if it must be moved to the left, make it negative)
if we have
2.3
in sciefitific notation, 0 places must be moved so it would be written as
2.3 x 10⁰
so yes, 0 can be an exponent, tho it would not be helpful and would just be more work
