Andre says "I wonder if I should add 4 units to the lengths of all of the segments?" What would you say in response to Andre? Explain reasoning. A polygon with side lengths 12, 6, 5, 4, 7, and 10.

problem:

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

f(5/2) = 10/3

i hope this !
