We can divide each digit by 7. So 56/7=8 and 21/7=3
so.... 8:3
Answer:
C: 23 cm
Step-by-step explanation:
This is the answer because:
1) Area of trapezoid is: (base1 + base2)/2 x height
2) In this case, it is 14 + 8 which is 22. 22/2 is 11.
3) Now we have to do 253/11 which is 23 cm.
Hope this helps! :D
Answer: The sides are increase by a factor of 3 and the angles remain the same.
When you are performing a dilation, you multiply the coordinates by 3. This will increase the length of all the sides by a factor of 3. However, the measures of the angles will remain the same. We call these similar figures.
