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:
I cant graph it for you but i can tell u the answer! i just saw that it has the full explanation better than mine!
Step-by-step explanation
Answer:
0.48
Step-by-step explanation:
1x3/56 then multiply it by 9
1x3 is 3
3 x 9 = 27
27/56 this fraction cant be reduced so if you count it or put it in a calculator you'll get 0.482143
Answer: 570.70 ft
Step-by-step explanation:
The perimeter is the distance around the entire parking lot.
The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.
The other two sides have the same measurement as this is a rectangle.
The perimeter of the parking lot is:
= (150.23 * 2) + (135.12 * 2)
= 570.70 ft
