Answer:
Fgh= -5x^3-^2+45x+9
Gfh= (3-x)(5x+1)(x+3)
I don't think you can do anything with the second one.
Step-by-step explanation:
10 = 2y + 4
6 = 2y
y = 3
18 = 10 + 2x
8 = 2x
x = 4
First, let's define our variables.
Let's call our width X(given)
and our length, since it's 10 shorter than 3 times the width, we can call our length:
3x-10
So, the perimeter of a rectange is equal to 2 times the length + 2 times the width.
So, when we plug our values in, we get

The perimeter is 8x-20
(18+ 18 +19+ 18 +24+ 21+ 21 +24 +23 +25+ 46 +28+ 21 +19)/14 =325/14≈<span>23.21</span>
