<span>4ab + 4a − 3b − 3
=4a(b + 1) - 3(b+1)
= (b+1)(4a - 3)
(b+1) and (4a - 3) are factors

Answer:
48
Step-by-step explanation:
Subtract the total of the 3 fish she is buying from the amount of money she has:
85 - (12 + 13 + 14) = 85 - 39 = 46
She has $46 to spend on crabs.
Divide the amount she has to spend by the price on one crab:
46 / 8 = 5.75
Since it isn't a whole number you need to round down, since she cant buy 0.75 of a crab.
She has enough money to buy 5 crabs.
Answer:
This is an exponential growth problem.
The growth rate is 4% (0.04).
The time is 10 years (10 years from 2005 to 2015)
A = P(1+i)t
A = amount spent in 2015
P = amount spent in 2005
i = interest rate expressed as a decimal
t = # years
A = 500(1.04)10
A = 500(1.480244)
A = 740.122 ==> 740 billion
