If f(x) = 3x + 10 and g(x) = 2x - 4, find (f+ g)(x). O A. (f+ g)(x) = 3x + 2x + 6
O B. (f+ g)(x) = -3x - 2x - 14
O C. (f+ g)(x) = 3x - 2x + 14
O D. (f+ g)(x) = 5x + 6

if x = 1, then the answer is 3.5

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.
