Answer:

A) P = 6n + 8

Step-by-step explanation:

Given:

Perimeter of the 1 triangle = 24

Perimeter of the 2 triangle = 30

Perimeter of the 3 triangle = 36

Let's check with option A.

P = 6n + 18, where "n" is the number in the figure.

Plug in n = 1, we get

P = 6(1) + 18

= 6 +18

P = 25 True.

Plug in n =2, we get

P = 6(2) + 18

= 12 +18

P = 30 True.

Plug in n =3, we get

P = 6(3) + 18

P = 18 + 18

P = 36, true.

Therefore, the answer is A. P = 6n + 18

Thank you.

What figure is a dilation of Figure A by a factor of 2?

stepan [7]

Answer: Bottom Right

Step-by-step explanation:

Since the scale factor is 2 all the lengths of the original should be multiplied by that scale factor. Don’t fall for the top left because 2•4 doesn’t equal 6. The top right is just completely off. The bottom left is if the factor is .5
