What is the perimeter, in units, of polygon EFGHJK?

38

Step-by-step explanation:

Add up all the sides together.

KE = 2

EF = 2

FG = 10

GH = 9

HJ = 8

JK = 7

Add all the sides and you get 38

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

you need to show us the graph.
