@3mar

OpenStudy (3mar):

Well, I am here!

OpenStudy (3mar):

In the first pic, it does not appear completely!

OpenStudy (newarf):

ok let me re do it

OpenStudy (3mar):

I am afraid of there is something useful for answering the question! Just that, no more

OpenStudy (3mar):

What I got is: simplify the expression: \[9(7-4)^2+9\] Is that right?

OpenStudy (newarf):

OpenStudy (3mar):

Ok let's proseed.

OpenStudy (3mar):

First, expand the parentheses to the power 2 Do it please

OpenStudy (newarf):

ok

OpenStudy (3mar):

What you got?

OpenStudy (newarf):

I don't understand accutualy

OpenStudy (3mar):

\[9(3)^2+9=9*(9)+9\] then multiply 9*9, you got: \[=9*(9)+9=81+9\]

OpenStudy (3mar):

then add 81 to 9, you will get \[81+9=90\] Done!

OpenStudy (newarf):

I got that already

OpenStudy (3mar):

Please tell me where are you stuck.

OpenStudy (newarf):

the two bottom ones and what is the solution to x/-6 = 10

OpenStudy (3mar):

what are two bottom ones? do you mean 6 and 7?

OpenStudy (newarf):

18

OpenStudy (3mar):

Easy In Sha' Allah

OpenStudy (3mar):

It says: \[\frac{ x }{ -6 }=10\] ok?

OpenStudy (newarf):

ok

OpenStudy (3mar):

What if you multiply both side by -6? Try that with me.

OpenStudy (newarf):

-60

OpenStudy (3mar):

That is it: \[-6\times \frac{ x }{ -6 }=10\times -6\] It will be \[x=-60\] are you convinced?

OpenStudy (3mar):

Very good!

OpenStudy (3mar):

What is next?

OpenStudy (newarf):

now 23 and 24

OpenStudy (3mar):

Ok

OpenStudy (3mar):

Do you know what is the absolute value or a number?

OpenStudy (newarf):

imeant 23 and 25 24 i can do

OpenStudy (3mar):

We are in 23 now.. Do you know what is the absolute value or a number?

OpenStudy (newarf):

dont know

OpenStudy (ronaldo7):

hey im still confused on my problem jiteshsmg

OpenStudy (3mar):

Ok The absolute value of any number gives you always its positive value. e.x\[\left| -13 \right|=13\] \[\left| -\frac{ 5 }{ \sqrt{2} } \right|=\frac{ 5 }{ \sqrt{2} } \\] Got it?

OpenStudy (newarf):

kinda

OpenStudy (3mar):

So the difference between the two is?

OpenStudy (newarf):

is zipo

OpenStudy (3mar):

\[\left| \frac{ -5 }{ \sqrt{2} } \right|=\frac{ 5 }{ \sqrt{2}}\]

OpenStudy (3mar):

difference does not mean "subtraction" It means that \[\left| -3 \right|=3\] and -3 does not change

OpenStudy (3mar):

Hope that helps Thank you for the medal!

OpenStudy (3mar):

25?

OpenStudy (newarf):

so ther are not any diverences

OpenStudy (3mar):

between what?

OpenStudy (3mar):

the difference is the FIRST one changes to 3 but the second doesn't It is clear now!

OpenStudy (newarf):

bettween [-3] and -3

OpenStudy (3mar):

not [-3] it is |-3| (absolute value=pick only the positive value)

OpenStudy (newarf):

which is greaterr

OpenStudy (3mar):

of course |-3|, as it results in 3, and 3 is greater than -3

OpenStudy (3mar):

25?

OpenStudy (newarf):

yes

OpenStudy (3mar):

25.a: what is the score of the first team after two games? It is from the table directly

OpenStudy (newarf):

-2

OpenStudy (3mar):

Good!

OpenStudy (3mar):

What is the score of the second team after two games? Similarly

OpenStudy (3mar):

Are you there?

OpenStudy (newarf):

-1

OpenStudy (3mar):

Great! Are you eating or doing something else? If you are busy, no problem, another time!

OpenStudy (newarf):

my computers acting up

OpenStudy (3mar):

Ok.

OpenStudy (3mar):

So which team has the highest score?

OpenStudy (newarf):

they are both the same

OpenStudy (3mar):

How, brother? The first team is -2 and the second is -1..................whose score is greater?????

OpenStudy (newarf):

what am i on write now team two won the first one i did not sleep las night

OpenStudy (3mar):

Hey, we don't calculate like that. Just look at the score of the first two games for both teams, which one has the greater score?

OpenStudy (3mar):

If a football team A has won first match with team B adn the result (4 goals to A: 1goal for B) and the second match team B has won and the result (2 for B: 1 for A) WHO HAS THE GREATER AMOUNT OF GOALS? oF COURSE A although every team won and lost one match

OpenStudy (3mar):

Are you there?

OpenStudy (3mar):

Seems you slept
