HELP ME. A triangle has side lengths of (2t+2)(2t+2) centimeters, (6t-7)(6t−7) centimeters, and (u-2)(u−2) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

-u-5+8t−u−5+8t
-7+u+8t−7+u+8t
-u+3t−u+3t
-u+4t-1−u+4t−1

step-by-step explanation:

the shape,the size and the distance

i think its doubled. let me know

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
