Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.

Answer:
6.85 oz
Step-by-step explanation:
13.7 ÷ 2 = 6.85
Answer: Three less than a number
Step-by-step explanation: z-3 means the three is subtracted from the unknown number.
<em>An unknown quantity less than three. would be 3 - z or z < 3</em>
The answer is B, because all 4 sides should be equal on a rhombus.
