![\large\boxed{A\ \cup\ B=[-5,\ 10]}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BA%5C%20%5Ccup%5C%20B%3D%5B-5%2C%5C%2010%5D%7D)
Step-by-step explanation:
Look at the picture.
The union of two sets A and B (A ∪ B) is the set of elements which are in A, in B, or in both A and B
The owners that drove between 50 and 65 miles are five owners.
Given:
12 rectangular planks
2 sides per plank
Length = 8 ft
Width = 3 ft
Area of a rectangle = Length * Width.
A = 8ft * 3ft
A = 24 ft²
24 ft² x 2 sides of a plank = 48 ft²
48 ft²/plank * 12 planks = 576 ft² is the total area Alex needs to varnish.
576 ft² ÷ 125 ft² = 4.608 pint or round to 5 pints
5 pints x $3.50/pint = $17.50 Total cost that Alex need to spend to varnish all the wooden planks.
