  A'(-3, 13)

Step-by-step explanation:

The transformation that moves a point 4 left and 8 up is ...

  (x, y) ⇒ (x -4, y +8)

The transformation that reflects a point across the y-axis is ...

  (x, y) ⇒ (-x, y)

Applied after the translation, the transformation of ∆ABC becomes ...

  (x, y) ⇒ (-(x -4), y +8) = (4 -x, y +8)

Then point A gets moved to ...

  A(7, 5) ⇒ A'(4 -7, 5 +8) = A'(-3, 13)

___

In the attached graph, the purple triangle is the result of the translation 4 left and up 8. Then the blue one is after reflection across the y-axis.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
