Answer: Lets divide by 8. My god, those coefficients are large.
x^3 - 8x^2 + 20x - 16 = 0
Possible integral roots are: +1, -1, +2, -2, +4, -4, +8, -8
If x = 2, f(x) = 8 - 32 + 40 - 16 = 0
Hence, x-2 is a factor.
Use synthetic division to get: x^2 - 6x + 8 = (x-4)(x-2).
Therefore, there are two integral roots: +2 and +4.

Step-by-step explanation:
200 divides into 1000 so that is part of the HCF.
x^2 and x^3 are present so the HCF contains x^2
y^2 and y^5 are present so the HCF contains y^2
HCF = 200*x^2 * y^2
Answer:
13.1 FEET OF WOOD FOR EACH HOUSE
Step-by-step explanation:
77.5-12=65.6
65.5/5= 13.1

5445 = 4500 i * 7
5445 = 31500i
i = 5445/31,500
i = 0.1729
i = 17.29%
Answer:
Step-by-step explanation:
Recall that the volume of a cube is given by:
Where <em>s</em> is the side length of the cube.
The edges of the cube has an original length of 2.25 feet. It increases by 1.25 feet per hour. In other words, the length <em>s</em> after <em>h</em> hours can be modeled by the equation:
Substitute. Hence, our function is:
