(V-8)(v + 4)
Simplify your answer

v^2 - 4v - 32

Step-by-step explanation:

Expand (v - 8) (v + 4) using the FOIL method.

apply the distributive property.

v (v + 4) - 8 (v + 4)

v x v + v x 4 - 8 (v + 4)

v x v + v x 4 - 8v - 8 x 4

simplify and combine like terms.

v^2 + v x 4 - 8v - 8 x 4

v^2 + 4 x v - 8v - 8 x 4

v^2 + 4v - 8v - 32

v^2 - 4v - 32

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,
