Suppose △ABC has coordinates A (2, 3), B (5, 1), C (4, 4), line m is the line with equation y = −5, and △ABC is mapped to △A′B′C′ by applying the glide reflection T⟨ −2, 1 ⟩∘ Rm. Select all the statements that are true about △A′B′C′.

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
