Answer:
Area = L^2 + 5L units^2
Step-by-step explanation:
Length = L
Width = L + 5 Because it is 4 longer than the length.
Area = W * L
Area = L * (L + 5)
Area = L^2 + 5L units^2
You can test it by substituting number in:
If the length is 4 and the width is 9 (4 + 5)
4 * 9 = 36 units^2
4^2 + 5 * 4 = 16 + 20 = 36 units^2
To start off, 50 - 2 is 48, to account for the chocolates he had left. 48 divided by 3 is 16, so Jack has 16 friends at the party!!
Find the mean of the numbers first. The find the difference that each one is from the mean (negative and positive differences). Find the mean of the differences and that is the MAD.
