Atriangle has a side lengths of (5.5x + 6.2y) centimeters, (4.3x+8.3z) centimeters and (1.6z -5.1y) cenrimeters which expression represents the perimeter, in centimeters of the triangle

mans really asked a question on the state test. whatever.

Step-by-step explanation:

9.8x + 1.1y + 9.9x

i got 10.28 but that rounds up to 10.3

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
