Answer:

$ac = ab + bc \\ 39 = 2x - 8 + x + 17 \\ 39 = 3x + 9 \\ 39 - 9 = 3x \\ 30 = 3x \\ x = 30 \div 3 = 10 \\ ab = 2x - 8 = 2 \times 10 - 8 = 20 - 8 = 12 \\ bc = x + 17 = 10 + 17 = 27 \\ thank \: you$

How many ways can six of the letters of the word 'PALINDROME' be selected and written in a row if the first two letters must be

IgorC [24]

BY permutation, There are 90 ways by which the arrangement of 'PALINDROME' takes place.

According to the statement

we have given that the word 'PALINDROME' and we have to find that the in how much ways this word can be arranged.

So, For this purpose, we use the permutation here

So, A permutation is a mathematical technique that determines the number of possible arrangements.

The word given is:

'PALINDROME' this contain 10 words and given 2 words M and E are in any order.

So, Permutation takes place with $P^{10} _{2}$ .

So,

$P^{10} _{2}$

Now solve this then

$P^{10} _{2} = \frac{10!}{(10 -2) !}$

And

$P^{10} _{2} = \frac{10!}{(8) !}$

$P^{10} _{2} = \frac{10*9*8*7*6*5*4*3*2*1}{(8*7*6*5*4*3*2*1) !}$

And then after take common from them and cancel it the equation become

$P^{10} _{2} = 10*9$

$P^{10} _{2} = 90$

90 ways are comes as the output.

So, BY permutation, There are 90 ways by which the arrangement of 'PALINDROME' takes place.

Solve and graph the absolute value inequality: |2x + 4| > 8

neonofarm [45]

Answer:

Step-by-step explanation:

To get rid of the absolute value bars you have to get two different equations which would be 2x+4>-8 AND 2x+4>8. Pay attention to the signs, if there is greater than or equal to then it would have a line underneath the sign, which neither of the equations should have since you haven't moved a negative. solve normally and you'll get -6 blank circle and 2 blank circle.
