Let x(t) = the length of a side of the square (cm) at time t (s).
The rate of change of x is given as

The area (cm²) at time t is
A = x²
The rate of change of the area with respect to time is

When A = 9 cm², then x = √9 = 3cm. Hence obtain

Answer: 12 cm²/s
Just divid
276/4 = 69
So it's 69
Answer:
<h2>The answer is - 2</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3, −7) and (−1, 1)
The slope is

We have the final answer as
<h3>- 2</h3>
