The product of two consecutive odd integers is 143. find all such pairs of integers.

x(x+2)=143
x^2+2x-143=0
(x+13)(x-11)=0
x=-13
x=11 solution 
x+2=13 solution
proof
11*13=143
143=143

l=w+4
thus (w+4)w=117
w^2+4w-117=0
(w+13)(w-9)=0
w-9=0
w=8 for the width
l=9+4=13 for the length.
proof
9*13=117
117=117 

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
