Show that the expression 3b - 4 + 6(b-9) is equivalent to the expression 9(b-6) – 4

Step-by-step explanation:

comment me if the answer is correct in the image above

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)

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.
