Answer:
Step-by-step explanation:
If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.
16x^ = (4x)^2 . . . . a perfect square
49 = 7^2 . . . . . . . a perfect square
-2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...
16x^2 -56x +49 = (4x -7)^2
_____
The sign in the binomial factors is the same as the sign of the middle term of the trinomial.

Answer:
0.636
Step-by-step explanation:
Let Aw, Ab, Bw, Bb the following events:
Aw = the ball drawn from urn A is white
Ab = the ball drawn from urn A is black
Bw = the ball drawn from urn B is white
Bb = the ball drawn from urn B is black
the probability that the transferred ball was black given that the second ball drawn was black is P(Ab | Bb)
By the Bayes' Theorem
Working out the calculations
rounded to three decimals
Answer:
48 square units
Step-by-step explanation:
Area = length x width
= 8 x 6
