Answer:
A. 6x + 4
B. 22 cm
Step-by-step explanation:
The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.
When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.
Assuming you are solving for x...

B is rational. B is the correct answer. B is rational.
$57.18 + 256.79 = 313.97
313.97 - 68.42 = 245.55
245.55 - 50.00 = 195.55
195.55 - 31.06 = 164.49
that’s your answer
