You had 12 the next day and the day after that you had 18
1. 1/2
2. The Y axis
3. 1 right and 1 down (1, -1)
16, 4x4 = 16 that's your 4x as many as red peppers and the red peppers is therefore 4 and 16+4 is an even 20
You solve the equation : t^2 - 9t - 90 = 0 ;
Δ = ( - 9 )^2 - 4 * 1 * ( - 90 ) = 81 + 360 = 441 ;
t1 = ( 9 +

) / 2 = 30 / 2 = 15 ;
t2 = ( 9 -

) / 2 = -12 / 2 = - 6 ;
The numbers are 15 and - 6 ;
