Haha, this is more a problem of reading the question right :)
(x^2-4x+4)/(x^2+10x+25) * (x+5)/(x^2+3x-10)
Upon factoring the numerator and denominators...
[(x-2)^2/(x+5)^2]*(x+5)/((x+5)(x-2)) so on the right side the (x+5)s cancel
((x-2)^2/(x+5)^2)*1/(x-2) which is:
[(x-2)^2]/[(x+5)^2*(x-2)] now you can see that (x-2)^1 cancels
(x-2)/(x+5)^2 or if you prefer it expanded...
(x-2)/(x^2+10x+25)
Answer:
6(4+3t)
Step-by-step explanation:
Well, some of the common factors that 24 and 18 share are 2, 3, and 6.
The greatest factor is 6.
Divide 24/6=4
Divide 18t/6=3
6(4+3t)
Because 6x4=24
and 6 x 3t= 18t
Answer:
The required probability = 0.9345
Step-by-step explanation:
Given that:
p = 0.17
n = 6
The required probability that two or less light bulbs are defective = (P<2)
(P<2) = P(X=0) +P(X=1) +P(X=2)
