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.

Answer:
1200 copies
Step-by-step explanation:
We can use ratios to solve
480 copies x copies
------------------ = -------------
4 minutes 10 minutes
Using cross products
480* 10 = 4x
Divide each side by 4
4800/4 = 4x/4
1200 =x
1g = 1000mg
40,000mg = 40g
10xg=40g
X=4
Hope this helps.
