Answer:
There is no solution to the systems of equation.
Step-by-step explanation:
Graph the system by using y=mx+b
Both systems are y=2/5x+5/2.
X=4 , I believe this is the right answer
Answer:

or

Step-by-step explanation:
The difference of two trinomials
and
is
This means that

or

If one of the trinomials is
then

or

1. If
then

2. If
then

Let, the width = x
Then,Length = 2x
Now, Area = l * w
A = (2x)(x)
128 = 2x²
x² = 128/2
x = √64
x = 8
In short, Your Answer would be 8 Feet
Hope this helps!
24.5 would be your answer :)
