B: ray
Rays are a linear formation that start at a point and continue forever in a direction. The photo shows a point on one end, and an arrow on the other indicating that it starts at the point and continues forever past the arrow.
You put the highest exponent power first, then you go down until you reach a regular number (a number with a variable goes before a normal number)
Ex: 5x^3+2x^2+4x+5
Answer:
18 sq ft
Step-by-step explanation: all you have to do is add the sides. 5+5=10
4+4= 8
10+8=18
This makes the most sense with the answers givin

The answer is A (2.5, 8, 15), since these integers are greater than 2.
