F(5) and F(-3)

Step-by-step explanation:

5>2 so,

F(x)=4x-9 for x=5

F(5)=4*5-9=11

-32 so,

F(x)=-2x-4 for x=-3

F(-3)=-2*-3-4=2

teleportation

step-by-step explanation:

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.
