Answer:
Width = x-1
Step-by-step explanation:
Given
Area of rectangle=A= x^4+4x^3+3x^2-4x-4
Length of Rectangle=L= x^3+5x^2+8x+4
We have to find width
Width of rectangle=W= ?
We know that the formula for the area of triangle is:
Area of Rectangle=Length*Width
A=L*W
Since we need the value of width, length will be moved to the left of equals to.
A/L=W
W= (x^4+4x^3+3x^2-4x-4)/(x^3+5x^2+8x+4)
After long division, we will get
Width=W=x-1

Question 1 Answer: both of them equal 20
Step-by-step explanation: when you add 9+3 it equals 12 then you add 8 and that makes 20. 9+8 also equals 17 then you add 3 which equals 20
