Answer:

use the quadratic formula

Step-by-step explanation:

from the equation a=6 b=-14 c=-9

from the quadratic formula

x = ( - b  {+ or - }   \sqrt{ {b}^{2}  + 4ac} ) \div 2a

therefore insert in the values of a, b and c

x = ( - ( - 14) + or -  \sqrt{ {(  - 14)}^{2}  + 4 \times 6 \times ( - 9)} ) \div 2 \times 6

x=2.858148594

X=-0.52481526

Tania took selfies with her 8 cousins. Each cousins is in 2 or 3 picture. There are exactly 5 cousins on each picture. How many
andreev551 [17]

Answer:

4

Step-by-step explanation:

How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )

We know that each cousin appear 2 or 3 times overall.

If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos

If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos

We know there's exactly 5 cousins per photo...

so we have to find a multiple of 5 cousins/photos that is between 16 and 24.

The only possibility is 20 cousins/photos.  20 / 5 = 4 photos.
