-28n - 4 + 2n - 8 = 66

-26n - 12 = 66

66 = -4(7n + 1) + 2(n - 4)

  • Distribute -4 inside the parentheses.

66 = -28n - 4 + 2(n - 4)

  • Distribute 2 inside the parentheses.

66 = -28n - 4 + 2n - 8

  • Combine like terms.

66 = -26n - 12

  • Add 12 to both sides.

78 = -26n

  • Divide both sides by -26.

n = -3

The perimeter of the cover of a math textbook is 34 inches. if the width of the cover is 7 inches, what is the length of the cov
Sauron [17]
The length would be 10 inches.
to find perimeter, you add length+length+width+width.
since both widths and both lengths have to be the same, u add the width 2 times or 7+7=14.
next u subtract 14 from 34 or 34-14=20. 
since u still have 2 lengths that are equal, u divide 20 by 2 or 20/2=10

hope this helps! :)
