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:
yes it is
Step-by-step explanation:
Answer:
y + 1 = 4(x + 3)
Step-by-step explanation:
Use the point-slope form of the equation of a straight line:
y - k = m(x - h), where (h,k) is a point on the line:
Here,
y + 1 = 4(x+3) (Answer 2 on the list)
