Simplify this expression.
m13 × m6 =
multiply coefficients and variables
m13 x m6 = 78m^2
since the variables are alike, you would just multiply them as you would do a normal multiplication problem! i used to have so much trouble with this omg. anyway, 13x6=78 so the answer would be 78m
i believe c
if x equals 28 then substitute it in the equation, 28+3y=28
next, subtract 28 from both sides, 3y=0
now that you have that its simple, y must equal 0
m13 × m6 =...
