Except in very elementary math, it's best NOT to use " x " to denote multiplication. Instead, use " * " or enclose the multiplicands within parentheses: (9x)(8y) = 72 xy

How did you get that?
OpenStudy (anonymous):
9 * 7 = 72 then just add y " 72y "
OpenStudy (texaschic101):

Where did you get 7 from i don't see it anywhere in the equation you gave
OpenStudy (anonymous):
nevermind..
pooja195 (pooja195):
Ok multiply
\[\huge~\rm~ 9y~\times 4y=?\]
(9)(4) =?
OpenStudy (anonymous):
72!
pooja195 (pooja195):
9 * 4 does not equal 72.Try again. Go over your 9 times table.
9 x 1= 9
9 x 2=18
9 x 3=27
9 x 4=?

oops, its 32
OpenStudy (anonymous):
36*
pooja195 (pooja195):
Good
y x y=?
OpenStudy (anonymous):
dunno.
pooja195 (pooja195):
You have 2 y's it would be y^2
now we have
\[\huge~\rm~8 + 36 y^2\times3\]

\[\huge~\rm~36 \times 3=? \]
OpenStudy (anonymous):
108
pooja195 (pooja195):
good you get 108y^2
and you're left with positive 8 you can't combine it because it is not a like term.
OpenStudy (anonymous):
yep
pooja195 (pooja195):
Yeah that's all it is :)
