The side length of a square is represented by the expression n - 1.5. which are equivalent expressions for the perimeter of the square?

a
n + n + n + n - 1.5 - 1.5 - 1.5 - 1.5

b
2(n - 1.5) + 2(n - 1.5)

c
2n - 1.5

d
4n - 1.5

e
2(n - 1.5)

f
4(n - 1.5)

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
