To determine which equation represents the hanger model, we need to understand the context of the problem.
If we assume the hanger model involves a weight supported by a string that has a total weight of 14, we can consider the following scenarios:
-
2r + 4 = 14: This equation suggests that 2 times a variable (perhaps representing some weight) and a constant (4) together equal 14.
-
2r − 4 = 14: This implies that 2 times a variable minus a constant (4) equals 14.
-
2 + r + 4 = 14: This equation indicates that the sum of 2, a variable (r), and 4 equals 14.
Given these interpretations, the most likely scenario for a hanger model would be the first option: 2r + 4 = 14, which accounts for some weights (2r) plus an additional weight (4) equalling the total (14).
Therefore, the equation that best represents the hanger model is:
2r + 4 = 14
