I think it’s 32 because, assuming the sides are equal, 12+20 equals 32

Which relation is a function? A. {(8,3), (-1,-1), (8,7), (-1,7)} B. {(1,6), (2,-3), (2,7), (3,7)} C. {(-3,6), (-3,9), (-1,4), (0

A. Not a function since x = 8 repeats. We have x = 8 pair up with y = 3 and y = 7 at the same time.
B. Not a function for similar reasons. Now x = 2 repeats. We have x = 2 pair up with y = -3 and y = 7
C. Not a function. We have x = -3 pair up with both y = 6 and y = 9 at the same time.
D. This is a function. Each x value is listed once and only once. Any input (x) leads to exactly one output (y). For choices A through C, it is possible to draw a vertical line through more than one point, thereby failing the vertical line test. In choice D, it is not possible to draw a vertical line through more than one point of this list. So this relation passes the vertical line test.
Answer: Choice D

A certain 50 cm spring will stretch (in cm) one fifth the weight (in kg) attached to it. How long will the spring be if a 35 kg weight is attached to it
Answer:
The value is 
Step-by-step explanation:
The length of the spring is 
The mass attached to it is 
Generally given from that the spring will stretch one fifth of the weight (in kg)attached to it , it then means that the new length of the spring whenever a weight is attached to it is mathematically represented as
