Answer:
P = (25.6g - 31.4)
Step-by-step explanation:
Given that,
The width of a rectangle = (8.1g−6.5) cm
The length of a rectangle, = (4.7g−9.2)
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
Substitute all the values,
P = 2(8.1g−6.5+4.7g−9.2)
= 2(12.8g-15.7)
= 25.6g - 31.4
So, the perimeter of the rectangle is equal to (25.6g - 31.4).
For the third space, use the the top right box.
For the fourth space, use the bottom left box.

Did you post it separately??
F(3)=-4(3)^2+4(3)-4
= -4(9)+12-4
= -36+12-4
F(3)= -28
