What times 3 equals 20

How can you find the mean absolute deviation (mad) for this set of data?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y

Divide. –40 ÷ –5 a –8 b 200 c -200 d 8
