Answer:
7. x equals 8
Step-by-step explanation:
the bigger rectangle had 4 on the side and the smaller had 2. we know dilation DO NOT occur by subtracting or adding so we can NOT conclude 4 was subtracted by 2. BUT It was DIVIDED by 2. so to check we are right..
4 divided by 2 =2
then..
16 divided by 2 = 8
Hope that helped! I could answer others but 7. was a random pick. please mark as brainliest! Thanks!
