Translate these expressions: A) fifteen less than twice a number:

B) six less half a number:

C) the quotient of a number and 2:

D) three times the sum of seven and a number:

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.
