Oliver picks a 4-digit even number that is greater than 3000.

Irina18 [472]

Answer:

Hello,

why not 700 ?

Step-by-step explanation:

$n=\overline{abcd}\\a\in \{3,4,5,6,7,8,9\}: 7\ possibilities\\b\in\{4,8\} :2\ possibilities\ :0 \ in\ USA\ is\ not\ a\ multiple\ of\ 4\\c \in\{0,1,2,3,4,5,6,7,8,9}: 10\ possibilities\\d \in \{0,2,4,6,8\}:5\ possibilities\\$

7*2*10*5=700

Impossible to reach 3000 since 2nd digit is 4 or 8.

Anon25 [30]

Step-by-step explanation:

6x²-13x+6

= 6x²-9x-4x+6

= 3x(2x-3)-2(2x+3)

= (2x-3)(3x-2)

Therefore, the roots are x=3/2 and x=2/3
