Solve for n.<br><br> n + 1 = 4(n – 8)
kolezko [41]
N + 1 = 4(n – 8)
Use distributive property for this part: 4(n – 8) ----> 4n - 32

n + 1 = 4n - 32

Get the variable on one side: 

n + 1 = 4n - 32
-n         -n

1= 3n - 32

Get the variable on its own:

1= 3n - 32 
+32       +32

33 = 3n

Divide by 3 on both sides: 

33/3 = 3n/3

n = 11

<h3>Solution 1</h3>

The figure (kite) is symmetric and covers half of the area of rectangle with sides 8 units aby 10 units

<u>The area of the rectangle:</u>
