a= 16x+16
b= 40x + 15
Step-by-step explanation:
We know that perimeter of a rectangle is

So therefore



Answer= A) that is perimeter is 16x+16
We know that area of a rectangle is l×b
So therefore


Answer = b) that is area is 40x + 15

Answer:
The equation is 
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
--> is negative because is a decreasing function
The y-intercept or initial value is

substitute
