Answer:
7d-5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length.
The perimeter of a regular pentagon is given by
P = 5s where s is the side length
35d -25 = 5s
Divide each side by 5
(35d-25)/5 = 5s/5
7d-5 =s
Each one of the sides is equal to 7d-5
Answer:
Step-by-step explanation:
- DC = AC = x is the radius
<u>Using the Pythagorean theorem, find x:</u>
- (x + 9)² - x² = 15²
- x² + 18x + 81 - x² = 225
- 18x = 225 - 81
- 18x = 144
- x = 144/18
- x = 8
Answer:
Answer in explanation
Step-by-step explanation:
The ratio of their ownership is 4:3 I.e J to T
Now we know that Terrence has 36 model cars. To find the number of model cars Jim own, we need to find the unit ownership. This is the same as 36/3 which is 12 cars.
This means Jim has 12 * 4 = 48 model cars.
Now we are looking at them selling 10 of their cars each. This would bring the number of model cars owned to be 38 and 26 respectively.
The ratio here would now be 38:26 which is same as 19:13. Of course this is different from 4:3, hence we can conclude that the ratio will indeed change
Answer:
14x+19x+8-8
=33x
because 8-8 is 0 always so the answer is 33X
