Simplify: 1/3 (6ab - 9b) + 2/3 (9ab + 12b)

1/3(6ab - 9b) + 2/3(9ab + 12b)

1/3(6ab - 9b + 2(9ab + 12b))

1/3(6ab - 9b + 18ab + 24b)

1/3(24ab + 15b)

1/3(3b)(8a + 5)

3 * 1/3b * (8a + 5)

b(8a + 5)

answer: can and shows the work

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
