Answer:
The first one is a function and the second one is not a function.
Step-by-step explanation:
180 plants
the area of a right triangle is: ab/2
side a = 8
side b = 15
8 x 15 = 120
120/2 = 60
Michael wants 3 plants for every square yard (multiply by 3)
60 x 3 = 180
it must be 5:4..I'm not sure.
