What’s the answer for this ?

baherus [9]

Answer:

Option B is the right option.

Here,

According to Question,

∆PNO ~ ∆ XYZ

i.e <PNO=<YXZ =37°

<PON= < YZX = 90°

hence, both triangles are similar by AA rule.

Hope this helps...

Good luck on your assignment....

What is -15xy + 25x factored

Oksanka [162]

Since -5x is common to both factors, hence the factored form is;

-5x(3y - 5)

<h3>Factoring equation</h3>

Given the exprssion -15xy + 25x

Fing the factors of each term

-15xy = -5 * 3 * x * y

25x = 5 * 5 * x

Since -5x is common to both factors, hence the factored form is;

-5x(3y - 5)

360 arrangements of 4 bridesmaids from her 6 closest friends are possible !

<u>Step-by-step explanation:</u>

Here we have , For a wedding the bride must select 4 bridesmaids from her 6 closest friends and must arrange them in order for the ceremony. We need to find How many arrangements of 4 bridesmaids from her 6 closest friends. Let's find out:

We know that formula for permutation is given by :

⇒ $nP_r = \dfrac{n!}{(n-r)!}$

According to question we have following parameters as : n = 6 , r = 4

⇒ $6P_4 = \dfrac{6!}{(6-4)!}$

⇒ $6P_4 = \dfrac{6!}{(2)!}$

⇒ $6P_4 = \frac{6(5)(4)(3)2!}{(2)!}$

⇒ $6P_4 =360$

Therefore , 360 arrangements of 4 bridesmaids from her 6 closest friends are possible !
