(8x^2-9y^2-4x)+(x^2-3y^2-7x)
First, get rid of the parentheses and combine like terms
(8x^2+x^2)(-9y^2-3y^2)(-4x-7x)
9x^2-12y^2-11x is your answer
True is the answer of the day
mean would be adding them all up and dividing by how many there is mean median mode and range but the mean absolute deviation would be actually can't tell you cuz I don't know myself but you could probably look it up I wish you the best of luck
