OH MY GOD PLEASE HELP!! :( [Image: Coordinate plane with points plotted at ordered pairs Q (–4, 4), R (2, 4), S (5, –3), T (2, –3), and U (–4, –3)]

Vertex Q is units from vertex R.
Vertex R is units from vertex T.
Vertex T is units from vertex S.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
