It can not be simplified because the numerator and denominator can not be divided between the same number, so that each results an integer number.

Answer:
X intercepts are points where a function intersects or cuts through the x axis where y=0.
Step-by-step explanation:
In the function given which is f(x) =x^2 +4x + 3 we see that this is a parabola of which when the graph is drawn it has a U shape so when finding x intercepts of this function it is those points on the function where the graph cuts the x axis and at those two points f(x)= 0, so here Mathieu had made a mistake of factorizing and equating the x intercepts for this function.
For finding the X intercepts let f(x) = 0
therefore 0= x^2 + 4x + 3 now we solve for x
0= (x+1)(x+3)
(x+1)= 0 or (x+3)=0
therefore x=-1 or x=-3
now if you substitute these values onto the function they give f(x)= 0,
f(-1) = (-1)^2 + 4(-1) + 3 = 0
f(-3) = (-3)^2 + $(-3) + 3 =0
now let us look at Mathieus answer which is x+1 = x+3 yes these x values do give the same y value but they are not equal because if you can actually solve this further you would not get a defined answer. Both these are factors of the function but are not actually equal as the function would not be able to be drawn if this was the case.
Answer:
174.7 cubic meters
Step-by-step explanation:
Formula:
V = (1/3)* π * r^2 * h
V = (1/3) * π * r^2 * 17.5
From knowing the circumference: 2*(π)*r = 19.4
r = 19.4 / (2*π)
V = (1/3)* π * (19.4 /(2π) )^2 * 17.5
V = (1/3) * (19.4)^2 * (1 / (4π)) * 17.5
V = (19.4^2 * 17.5 divided by (12π)
V = 6,586.3 / (12π)
V = 6,586.3 / 37.699111842
V = 174.7070336193518 cubic meters
So if we do 60,000*0.18=10,800 which is the number the price will decrease annually.
1=49,200
2=38,400
3=27,600
4=16,800
:D Hope this helps!
