I need help on how to solve this so anything is good :)
DanielleElmas [232]

Answer:

STUV is a square

Step-by-step explanation:

segment length² = (x-x₁)² + (y-y₁)²

ST²: (-9 - 1)2 + (14 - 10)² = (-10)² + 4² = 116   (the rest follow this formula)

TU² = 116    TV² = 232    SU² = 232   SV² = 116   UV² = 116

ST = TU =SV = UV  (4 sides congruent)

TV = SU  (diagonal equal)

This is a square

Step-by-step explanation:

let the number = X

If 139 is added, it becomes= X +139

the result becomes 44less than four time the number

= 4(39)-44 = 156-44 =112

the set up equation becomes

X +39 = 112

solving for the value of X

X = 112-39

X = 73
