Answer:

x = 3.5

Step-by-step explanation:

diameter = radius × radius

d= ( 3x + 1 ) + ( x + 8 )

3x + 1 = x + 8

subtract 1 and x

2x = 7

divide by 2

x = 3.5

the function t(n) 8n represents the number of tires t(n) that are needed for n trucks. if t(n)=200. what is the value of n?
mr_godi [17]

Step-by-step explanation:

if I understand correctly, then the function is

t(x) = 8x

now we know, that for a specific n

t(n) = 200

that means

200 = 8n

n = 200/8 = 25

the function tells us, that for 25 trucks we need 200 tires.
