Need help with this
Stells [14]

Answer:

38 = D

Step-by-step explanation:

The 3 angles of a triangle equal 180 degrees

<B + <C + <D  = 360

7x+ 12 + 2x+13 + 2x+ 12 =180

Combine terms

11x+37 = 180

Subtract 37 from each side

11x+37-37 = 180-37

11x =143

Divide by 11

11x/11 = 143/11

x =13

We want to find angle D

2x+12 = D

2(13) + 12 = D

26+12 = D

38 = D

Write 25*24*23*22 as a quotient of factorials and as a permutation
Kipish [7]

Answer:

(a)

25\times 24\times 23\times 22=\frac{25!}{21!}

(b)

25\times 24\times 23\times 22=P(25,4)

Step-by-step explanation:

Quotient of factorials:

we are given

25\times 24\times 23\times 22

we can multiply top and bottom term by 21!

25\times 24\times 23\times 22=\frac{25\times 24\times 23\times 22\times 21!}{21!}

we can write as

25\times 24\times 23\times 22=\frac{25!}{21!}

As a permutation:

we know permutation formula

P(n,r)=\frac{n!}{(n-r)!}

now, we can compare and find 'n' and 'r'

n=25

n-r=21

we can plug back n=25

25-r=21

r=4

so, we can write

25\times 24\times 23\times 22=P(25,4)
