Answer:

(4x + 7) (4x - 7)

Step-by-step explanation:

16x^2 will be broken down to 4x and 4x since when you multiply them, it will equal 16x^2

Then -49 can be broken down to 7 & -7 since 7 x (-7) = -49

What is the distance between (-5, 5) and (1, -2)
Murrr4er [49]

Answer:

\displaystyle d=\sqrt{85}\text{, or about 9.22 units}

Step-by-step explanation:

          We will use the distance formula to solve.

\displaystyle d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}

\displaystyle d=\sqrt{(1--5)^2 +(-2-5)^2}

\displaystyle d=\sqrt{(6)^2 +(-7)^2}

\displaystyle d=\sqrt{36+49}

\displaystyle d=\sqrt{85}\text{, or about 9.22 units}

In how many ways can 7 persons be arranged in a line such that (a) two particular persons are never together.
ivanzaharov [21]

Answer:

3600 ways

Step-by-step explanation:

person A has 7 places to choose from :

→ He has 2 places ,one to the extreme left of the line ,the other to the extreme right of the line

If he chose one of those two ,person B will have 5 choices and the other 5 persons will have 5! Choices.

⇒ number of arrangements = 2×5×5! = 1 200

→ But Person A also , can choose one of the 5 places in between the two extremes .

If he chose one of those 5 ,person B will have 4 choices and the other 5 persons wil have 5! Choices.

⇒ number of arrangements = 5×4×5! = 2 400

In Total they can be arranged in :

1200 + 2400 = 3600 ways
