Answer:
x = 7
Step-by-step explanation:
40/16 = 2.5 scale factor that it's being enlarged by. So, 16 x 2.5 =40
45/2.5 = 18
2x + 4 = 18
- 4 both side
2x = 14
÷2 both side
x = 7
Answer:
<h2>x=7</h2>
Step-by-step explanation:
all the difference between these polygons is that the left one is 2.5x bigger than the one on the right (I found this out by doing 40/16 which is 2.5)
so now I need to divide 45 by 2.5
45/2.5=18
Now I know that
2x+4=18
-4 from both sides
2x=14
divide by 2
x=7
