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

5/6 + 3j = -2/3 I need to find the value of j
weeeeeb [17]

5/6 + 3j = -2/3

Multiply all terms by 3.

5/2 = 3j - 2

Multiply all terms by 2.

5 = 6j - 4

Add 4 to both sides.

9 = 6j

Divide both sides by 6.

j = 1.5
