One example is the idea of two parts of a book that open up. Each flat part is a plane and the two planes intersect along the spine of the book.
Another example would be a wall intersecting with the floor. Both are flat surfaces.
A third example would be a laptop's screen as one plane and the keyboard as the other plane. They intersect at the hinge of the laptop.
For each example, the surface has a finite amount of area and it doesn't extend forever in all four directions. Theoretically, a plane is where the flat surface extends in all four directions infinitely. Though of course, real life has limitations but the idea is still applicable in a way.
Note how for each example, the two planes intersect to form a line. Also, each plane must be flat without bending or curving in any way.
Answer:
They have three sides.
Step-by-step explanation:
Only E) is true. If I were to arbitrarily pick x = 2.2 and y =1.1, then I could show that A), B), C), and D) to be false, given x/y = 2.2/1.1 = 2 (which is an integer). However for E), if we define x/y = n where n is an integer, then by rearranging terms, we can show x = n*y where n still equals an integer and our original equation is still valid.
1.2 Inches, It moves 0.3 inches in 1 hour so if in 1 hour it moves 0.3 and in 2 0.6 and in 3 0.9 so in 4 hours it will move 1.2 inches
