Yolanda makes wooden boxes for a crafts fair she makes a hundred boxes like the one showing and she wants to oaint all the outside faces

what do you mean i dont see anything "showing" and do you mean paint instead of oaint?

Step-by-step explanation:

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 !
