Guys can you please factor this out for me

21a+8xy^3 −24y^2−7axy

(7 a - 8y^2) x (3-y)

Step-by-step explanation:

21a+8xy^3 −24y^2−7axy

factor out 3 from the expression

3( 7 a - 8 y^2) + 8y^3 - 7 a y

3(7 a - 8 y^2) - y x (-8y^2 + 7 a)

Factor out 7 a - 8y^2 from the expression

(7 a - 8y^2) x (3-y)

= (7 a - 8y^2) x (3-y)

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

25/6 hope it : )
