Surface Area Of Triangular Prism

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

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 !
