t = 1/(1/22)
t = 22 hr
The insect will need 22 hours to crawl a distance of 1 mile.
The bacteria population will be 8,000 bc 2,000 x 2= 4,000 that’s after 4 hours then you double that agin 4,000 x 2= 8,000
Answer:
(x + 11 ) * ( x - 11)
Step-by-step explanation:
The expression:
x² - 121
is a difference of squares
We notice that √x² = x and √121 = 11
Then
( x² - 121 ) = ( x + 11 ) * ( x - 11 )
If we multiply
( x + 11 ) * ( x - 11 ) = x*x - 11*x + 11*x - (11)*(11)
( x + 11 ) * ( x - 11 ) = x² - 121
That is what we want to probe
