Answer:

Symmetric property of equality

Step-by-step explanation:

Symmetric property of equality states that:

if a = b

then;

b = a

For example:

if 7 = x+y

then:

x+y =7

As per the statement:

if $p = q$

by symmetric property of equality,

$q= p$

Therefore, Symmetric property of equality that justifies the statement: if p=q, then q=p

Answer : - Symmetric property of equality tells that for all real numbers p and q, if p=q then q=p which means if we interchange the sides of an equation then the equation is still a true statement .

For example :-

1. We know that 4+5 =9 then by symmetric property we can also say that 9=4+5.

2. If 5x+5=7 then by symmetric property of inequality 7=5x+5.

Factor. Check by multiplying.<br> x^2 - 3x

bazaltina [42]

Both term has factor of x

So that would be x² - 3x = x·x - 3·x = x( x-3 )

You can check by distribute x back to x-3:

x( x-3 ) = x·x - 3·x = x² - 3x. So our answer is correct.

Final answer: x( x-3 )

Hope this helps.

So this has to do with permutations and honestly I need an explanation on how I can figure these out.

AnnZ [28]

Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....

u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.

I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me
