Answer:
Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
Step-by-step explanation:
It is equal to 2(x)^3 because pemdas, exponnets come before multiplication so it would be x^3 then multiply whatever that is by 2
2x^3 is answer (4th choice)
Answer:
(- 2, 4 )
Step-by-step explanation:
y = 2x + 8 → (1)
y = - 2x → (2)
substitute y = 2x + 8 into (2)
2x + 8 = - 2x ( add 2x to both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
substitute x = - 2 into (2)
y = - 2(- 2) = 4
solution is (- 2, 4 )
Original equation x = yz / a solve for a
xa = yz
a = yz / x
Well first lets find the ROC (rate of change) in the sets of data.
1990 -> 134
2000 -> 139
so lets find the difference from the years given
2000-1990=10 so there is a 10 year gab
139-134=5 so there is a 5 million increase in the population
so divide 10 by 5 which gives us 2, so every year there is a 2 million increase in the population. so from 2000 to 2014 there is 14 years, so
14 x 2= 28, then add that to the latest population data
139+28=167
so the population in 2014 would be 167 million
Hope this helped!!
