Add up all sides lengths:
s+6 + s+6 + s + s + 2s = 102
solve for s:
6s + 12 = 102
6s = 90
s= 15
The lengths of sides are as follows:
15, 21, 21, 15, 30 inches
I hope that

Answer:
Equivalent expression for n x a = a+ a+a+a....n times
Step-by-step explanation:
Given: Expression for n x a .
To find : Write an equivalent expression for n x a using only addition.
Solution : We have given that n x a .
Here, we can say Sum of a is n times.
We can rewrite it n x a = a+ a+a+a....n times.
Example : 3 x 2 = 2 +2+ 2.
6 = 6 ( true)
Therefore , equivalent expression for n x a = a+ a+a+a....n times.
Answer:
909.8 millibars.
Step-by-step explanation:
The mean sustained velocity, v be determined by the equation:
, where p is the air pressure, in millibars, at the center of the hurricane.
Given that: v=64 meters per second, we are to <u>find the value of p.</u>
<u />
<u />
The approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second is 909.8 millibars.
