Step-by-step explanation:
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
The "constant of proportionality" is the value that relates the two amounts<span>Example: you are paid $20 an hour (continued)<span>The constant of proportionality is 20 because:</span></span><span><span>Earnings = 20 × Hours worked</span></span>

A 3-x because 3 equal f and g equal x for the second equation
Circle area = PI * radius^2
10 foot circle = PI * 100 = 314.159265
