Do the lengths 5, 9, and 14 form a right triangle? Explain your reasoning.

No, because they are not true for Pythagorean theorem.

Step-by-step explanation:

5²+9²= 106

14²=196

106 is not equal to 196.

For 5,9,14 to be sides of a right triangle,

5²+9²=14²

which is not true.

So, this is not a right triangle

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
