Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that 
is the same as a*d = b*c
is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4
<h3>Answer:</h3>
<h3>Step-by-step explanation:</h3>
Answer:
B
Step-by-step explanation:
To get x by itself, you have to divide each side by the number that x is attached with.
For the first one, divide each side by 3 so that x is by itself and 21/3 is 7 to get x<7
Do the same with the other side but with 5 to get x>11
