Answer:

<em>Perimeter = 6x + 5.</em>

Step-by-step explanation:

The perimeter is the sum of the three sides.

Perimeter = 3x - 2 + (-5x) + 8x + 7

= 3x - 2 - 5x + 8x + 7

= 3x - 5x + 8x - 2 + 7

= 6x + 5.

Andrew has three times as many pencils as Noah and five pens he has 17 pens and pencils altogether how many pencils does Noah ha
Novay_Z [31]

9514 1404 393

Answer:

  4

Step-by-step explanation:

The distributive property does not appear to be involved in this question.

Let n represent the number of Noah's pencils. Then Andrew's total is ...

  3n +5 = 17

  3n = 12 . . . . . subtract 5 from both sides

  n = 4 . . . . . .  divide both sides by 3

Noah has 4 pencils.
