P left triangle = (2x+8) + (2x+7) + 2x

 combine like terms

P left =6x+15

P right triangle = 2x+ 2x+ (3x+7)

combine like terms

     7x+7

since the perimeters of the triangles are equal, set them equal

6x+15 = 7x+7

subtract 6x from each side

15 =x+7

subtract 7 from each side

8 =x


AB = 2x+8 = 2*8 +8 = 16+8 = 24

BC =2x+7 = 2*8+7 = 16+7 = 23

CA = 2x =2*8    = 16


PQ = 2x = 16

QR = 2x = 16

PR = 3x+7 = 3*8+7 = 24+7 = 31

If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a
Levart [38]
An even function implies f(x) = f(-x)
We know that if (6,8) is a point on the graph, then f(6) = 8
By definition, f(6) = f(-6) = 8
So (-6, 8) is also a point on the graph.
