First observe that x=-1 is a root of the equation. Use long division to divide x^3-3x^2+x+5 by x+1, we find that (x^3-3x^2+x+5)/(x+1)=(x^2-4x+5). Now we need to find the roots of x^2-4x+5.
x^2-4x+5=0,
x^2-4x+4=-1,
(x-2)^2=i,
x-2=i or -1,
x=2+i or 2-i.
The three roots are 2+i, 2-i, -1.
Answer:
49.62
Step-by-step explanation:
You can start by dividing the shape into 2 separate rectangles to make calculating the area easier.
9.3 x 2.4 = 22.32
10.5 x 2.6 = 27.3
Then, add the areas of the two separate rectangles to find the total area of the shape.
22.32 + 27.3 = 49.62. Hope that helped

Step-by-step explanation:
The product of <em>a</em> and <em>b</em> is equal to <em>a · b.</em>
Let <em>w - width</em> and <em>l - length</em>, then the product of the width and the lenght is
<em>w · h = wh</em>
