Answer:

Step-by-step explanation:
A. Scale factor
When you dilate an object by a scale factor, you multiply its line lengths by the same number.
If EF/AB = 13/7, the scale factor is 13/7.
B. Length of EF

C. Area of EFGH
If the lengths in a shape are all multiplied by a scale factor, then the areas will be multiplied by the scale factor squared.
ABCD is dilated by a scale factor of 13/7, so its area is dilated by a scale factor of

The area of its dilated image EFGH is

Answer:
the greatest common factor is 3
No, actually the method is not correct. Adiya needed to take x2 and subtract it from 20x. she would then get 6 = 18x. Have in mind also that she needed to divide 18. So 6 = 18x turns into 6=X. That is why is incorrect
There are 30 students in the classroom; 40% are men and 60% are women. How many men and women are in the classroom?
40/100 = 2/5 60/100 = 3/5 30 ÷ 5 = 6 3 × 6 = 18 so 18 are women 2 × 6 = 12
so there are 12 men.
Answer:
15/30
Step-by-step explanation:
To get from 10 to 30 you have to muliply by 3.
So you do that to the 5 too.
5 * 3 = 15
