Answer:

8 x 4 wheels per skate = 32

32 x 2 shoes per person = 64

7 x 2 wheels per bike = 14

9 x 4 wheels per skate board = 36

-4x^4 - 3x^3 - 29x^2 - 114 where x= -4

tatiyna

Answer: -1410

Step-by-step explanation:

Let's start by subbing in -4 for x

$-4x^4 - 3x^3 - 29x^2 - 114\\-4(-4)^4-3(-4)^3-29(-4)^2-114$

Now we can solve

$-4(256)-3(-64)-29(16)-114\\-1024--192-464-114\\-832-464-114\\-1296-114\\-1410$
