38 cm sum of all sides is equal to the perimeter
Y = mx + b
m: slope
b: y -intercept
so the y intercept is -4 or (0,-4) as a coordinate

B. 
Step-by-step explanation:


Answer is x is less than 4
Answer:
The area is changing at the point of 
Step-by-step explanation:
From the given information:
Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w
where;
L = length and w = width of the rectangle
Suppose the Length L is twice the width w
Then L = 2w --- (1)
From The area of a rectangle
A = L × w
A = 2w × w
A = 2w²
Taking the above differentiating with respect to time

At the time t

Replacing the values back into equation 2, we get:
