Answer: P = 25n + 35

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of length and width.

P = 2(l +w)

P = 2((8.5n+9) + (4n +8.5))

P = 2(12.5n +17.5)

P = 25n + 35

Answer:

8.5n+9+4n-8.5+8.5n+9+4n-8.5

take the like terms together:

8.5n+4n+8.5n+4n=25n

9-8.5+9

=9.5

final answer=25n+9.5

R=P over I squared. Solve for I.

kirza4 [7]

Answer: I=sqrt(P/R)

Step-by-step explanation:

R=p/I^2

Multiple l squared on both sides...

(I^2) R=p/l^2 (l^2)

R(I^2)=p

Separate I by dividing both sides by R...

I^2=p/R

Square root both sides...

I=sqrt(P/R)
