C.
A square has 4 sides, the perimeter of a square is hence an addition of the length of the 4 sides. the answer (c) clearly shows it.
Answer:
Graph A: y = (1/2)x - 2
Step-by-step explanation:
2x−4y=8 in slope-intercept form is -4y = -2x + 8, or y = 1/2x - 2
The slope of this line is 1/4 and the y-intercept is -2. This is represented by Graph A.
Answer:

Step-by-step explanation:
From the question we are told that:
Mass 
Amount of NaCl IV 
Rate 
Generally the equation for fluid rate be for your IV pump is mathematically given by

Since
Rate is
30ml/kg/hr at 1kg patient Weight
Therefore


Where’s the rest of the question? Am I supposed to solve this completely?
