Last question i need with. (40 points)

x^4 -x^3 -4x^2 -3

Step-by-step explanation:

f(x) = x^4 -x^2 +9

g(x) = x^3 +3x^2 +12

We are subtracting

f(x) -g(x) =x^4 -x^2 +9 - ( x^3 +3x^2 +12)

Distribute the minus sign

x^4 -x^2 +9 -  x^3 -3x^2 -12

I like to line them up vertically

x^4      -x^2 +9

-  x^3 -3x^2 -12

x^4 -x^3 -4x^2 -3

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

1. 3

2. 4

3. 1

hope this ! have a great day.
