2x-3y = 8
Add 3y on both sides
2x = 8 + 3y
Subtract 8 on both sides
3y = 2x - 8
Divide 3 on both sides
Add 3y on both sides
2x = 8 + 3y
Subtract 8 on both sides
3y = 2x - 8
Divide 3 on both sides
Answer:
C
Step-by-step explanation:
From the given coordinates
A(6, 0), B(0, 0) then AB = 6 - 0 = 6
B(0, 0), C(0, 8) then BC = 8 - 0 = 8
To calculate AC use Pythagoras' theorem on the right triangle formed
AC² = AB² + BC² = 6² + 8² = 36 + 64 = 100
Take the square root of both sides, hence
AC = = 10
Perimeter = AB + BC + AC = 6 + 8 + 10 = 24 → C
