Trong mặt phẳng và hệ trục tọa độ oxy cho phép vị trí tâm I(2;3) tỉ số k=-2 biến điểm M (-7;2) thanh M' có tọa độ

no

step-by-step explanation:

6 and 24

step-by-step explanation:

6 x 4 = 24

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

b and c are the correct answers.

good luck on the quiz! : d
