Yuliya22 [10]

Answer:

See below

Step-by-step explanation:

<u>The sequence given</u>

6, 19, 58, 175

<u>We see the pattern: triple the previous term plus 1</u>

2) 19 = 6*3 + 1
3) 58 = 19*3 + 1
4) 175 = 58*3 + 1

<u>Next two terms</u>

5) 175*3 + 1 = 526
6) 526*3 + 1 = 1579

<u>Following two terms</u>

7) 1579*3 + 1 = 4738
8) 4738*3 + 1 = 14215

Answer:

table: 14, 16, 18
equation: P = 2n +12

Step-by-step explanation:

Perimeter values will be ...

rectangles . . . perimeter

1 . . . 14

2 . . . 16

3 . . . 18

__

The perimeter of a figure is twice the sum of the length and width. Here, the length is a constant 6. The width is n, the number of rectangles. So, the perimeter is ...

P = 2(6 +n) = 12 +2n

Your equation is ...

P = 2n +12 . . . . . . . . perimeter P of figure with n rectangles.

_____

<em>Additional comment</em>

You may be expected to write the equation using y and x for the perimeter and the number of rectangles. That would be ...

y = 2x +12 . . . . . . . . . perimeter y of figure with x rectangles
