Aaaaaaaaaaaaaaaa and bbbbbbbbbbbbbbb
Answer:
B
Step-by-step explanation:
B
x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.
A basket contains red, green, and yellow peppers. A pepper is
selected at random. If P(red) = and P(yellow) = 1 what
is P(green)?
yes, it would be green.
R = {10; 15; 20}
S = {20; 25}
R U S = {10;15; 20; 25;
Say r is rational. Suppose for a second, that s is not. Then, r+s is irrational. But this contradicts the fact that b is rational.
So, if one root is rational, then the other root is also rational
