2x+9=-3
-9 -9
2x=-12
divide by 2
x = -6
The answer: 54 inches
Explanation: those triangles are similar which means if one side is multiplied by 3 then all the other sides should be multiplied by 3 so since the DF=15=3•AB we need to multiply seven by 3 and we’ll get 21. For the perimeter, we write: 21+15+18=54.
Answer:
n=9
Step-by-step explanation:
