@10115658 could you help?

Answer 2

add up the sides of each triangle

Answer 3

big triangle: 6x,14x,1x = 21x
small triangle= -3x, 7x,3x= 7x

Answer 4

no, you add the x values together and the non x values together.

Answer 5

For the first triangle we have
4x + 2 + 7x + 7 + 5x - 4

Answer 6

Add up all the x-values
4x + 7x + 5x = 16x

Answer 7

Then add up the non x values
2 + 7 - 4 = 5

Answer 8

So the perimeter is 16x + 5

Answer 9

ohh so
big triangle: 16x +5
small triangle: 4x + 5
