Answer: one hundred and twenty five million
There were 200 books sold. so, they need to sell 300 more to have 500 total books sold.
Answer:
6y² - 20y + 6
Step-by-step explanation:
Use FOIL method
(3y - 1)(y-3) = 3y*y + 3y*(-3) + (-1)*y + (-1)*(-3)
= 3y²- 9y - y + 3 {add the like terms}
= 3y² - 10y + 3
2(3y - 1)(y - 3) = 2 ( 3y² - 10y + 3)
= 2*3y² - 2*10y + 2*3
= 6y² - 20y + 6
Answer:
a₄=8n+1= -39.
Step-by-step explanation:
1) if a₁=3n; a₃=5n-6 and a₅=11n+8, then it is possible to calculate the difference according to 0.5(a₅-a₃)=0.5(a₃-a₁). Then
2) 0.5(11n+8-5n+6)=0.5(5n-6-3n); ⇔ 6n+14=2n-6; ⇔ n= -5.
3) if n=-5, then the 4th term is:
or a₄=-39.
Answer:
the last option (-5k+4)-8 + 6k
Step-by-step explanation:
-8(-5k+4)+6k
to simplify, begin by distributing the -8 so that parentheses are removed:
=(-8)(-5k) + (-8)(4) + 6k
=40k - 32 + 6k
combine 'like terms':
46k-32
the only answer which simplifies to 46k-32 is the last option:
the only difference between the original problem and the last option is that the -8 value is behind the parentheses instead of in front of it; it simplifies to be 46k-32
