To multiply mixed numbers we need to convert them to fractions.
![[A\frac{b}{c}=\frac{Ac+b}{c}]](https://tex.z-dn.net/?f=%5BA%5Cfrac%7Bb%7D%7Bc%7D%3D%5Cfrac%7BAc%2Bb%7D%7Bc%7D%5D)

⇒ 
⇒ 
Then we simply multiply the numerators and denominators.
⇒
Then we convert back to mixed fraction by dividing numerator by denominator and writing the quotient as whole number with fraction (remainder as numerator and denominator being the divisor)
⇒
miles.
∴ Distance he covers in
of an hour =
miles.

Answer:
=-18x^2+78xy-24y^2
Step-by-step explanation:
(-2x+8y)(9x-3y)
-18x^2+6xy+72yx-24y^2
-18x^2+(6xy+72xy)-24y^2
=18x^2+78xy-24y^2
