Let
x--------> original length side of a square
we know that
area rectangle=length*width
area=126 in²
length=(x+8)
width=(x-3)
so
126=(x+8)*(x-3)------> x²-3x+8x-24=126----> x²+5x-150=0
using a graph tool------> to resolve the second order equation
see the attached figure
the solution is
x=10 in
the answer is
the original length side of a square is 10 in

Answer:
B>18
Step-by-step explanation:
I like to rewrite it like this:
b-8>10
Now solve:
b>18
Answer:
