The area of a rectangular garden is represented by the polynomial shown below. X^2+19x-42 What are the dimensions (length and width) of the rectangular garden?

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

i have no clue what you just said. write a question in english?

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
