2/5 + 3/5 = 5/5= 1
Which means 3+1=4
The ? Is 3/5
If a polynomial P(x) has a zero equal to
a, then (x-a) is a factor of this polynomial. So if a polynomial has zeros
a,
b and
c then it has we could write:
P(x)=(x-a)(x-b)(x-c).
Here we can clearly see that a, making the left hand side 0 because of the factor (x-a), makes the left hand side 0 as well. This means that P(a)=0. This illustrates the discussion above.
Thus, substituting a, b, c with <span>−3, 3, 2 we can write P(x)=(x+3)(x-3)(x-2).
We can expand the right hand side to have the polynomial in standard form:
</span>
We see that all conditions are satisfied.
<span>
Answer: </span>

total of ages now is 67 + 4 + 4 = 75
S=shelly
M= Michelle
Michelle is 3 yrs younger than Shelly so use S-3
S +M = 75
replace M with S-3 to get:
S +S-3=75
2S=78
s=39
So shelly is 39
Michelle is 3 years younger = 39-3 = 36
Answer:
Hey there!
First, we want to find the radius of the circle, which equals the length of line segment AC.
Length of line segment AC, which we can find with the distance formula: , which is equal to 5.
The equation for a circle, is: , where (h, k) is the center of the circle, and r is the radius.
Although I don't know the center of the circle, I can tell you that it is either choice B or D, because the radius, 5, squared, is 25.
Hope this helps :) (And let me know if you edit the question)
