OpenStudy (janu16):

alright so we are replacing all x by 3

OpenStudy (janu16):

so \[\frac{ 1 }{ 3 }(3(3)+105)\]

OpenStudy (janu16):

so whats 3 times 3?

OpenStudy (janu16):

@nautika27

OpenStudy (nautika27):

9

OpenStudy (janu16):

then add 9 plus 105 and what do you get?

OpenStudy (nautika27):

114

OpenStudy (janu16):

114 divided by 3 is what?

OpenStudy (nautika27):

38

OpenStudy (janu16):

so 38 is your final answer. hope it helped :)

OpenStudy (nautika27):

OpenStudy (nautika27):

OpenStudy (nautika27):

this is what it looks like

OpenStudy (janu16):

ok so first we replace x with 4 like we did previously so

OpenStudy (nautika27):

ok

OpenStudy (janu16):

so \[(4+\frac{ 4 }{ 2 })^2\]

OpenStudy (janu16):

simplify to 4+2)^2

OpenStudy (janu16):

so what 4 plus 2

OpenStudy (janu16):

@nautika27

OpenStudy (nautika27):

6

OpenStudy (janu16):

OpenStudy (nautika27):

162

OpenStudy (janu16):

ok so its not b but first we are gonna replace x with 5 so

OpenStudy (janu16):

so \[30/5+3^2\]

OpenStudy (janu16):

what is 3^2?

OpenStudy (janu16):

@nautika27

OpenStudy (nautika27):

6

OpenStudy (janu16):

yes we have \[\frac{ 30 }{ 5 }+9\]

OpenStudy (janu16):

so what is 30 divided by 5?

OpenStudy (nautika27):

6

OpenStudy (janu16):

what is 6 plus 9?

OpenStudy (nautika27):
