Holly finds that (11m – 13n + 6mn) – (10m – 7n + 3mn) = m – 20n + 9mn. what error did holly make? she only used the additive inverse of 10m when combining like terms. she added the polynomials instead of subtracting. she only used the additive inverses of –7n and 3mn when combining like terms. she did not combine all like terms.

A.)she only used the additive inverse of 10m when combining like te

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
