The answer is 40 because they're are 4 groups of ten so it would go like 10,20,30,and 40.=)
3. (x + 1)/4 = 3 / 6
x + 1 = 3/6 x 4 = 2
x = 1
Scale factor = 6 / 4 = 1.5
Ratio of perimeters = 2 : 3
4. x / 21 = 20 / 15
x = 20 / 15 x 21 = 28
Scale factor = 20 / 15 = 4/3
Ratio of perimeters = 3 : 4
If there are 14 tens, that is 14 multiplied by 10. 14 x 10 = 140.
140 is the answer.
Hope this helps :)
