ASHA 777 [7]3 years ago
3 0

Answer:

x ={0; - 1 ;  2 ;  1}

Step-by-step explanation:

x¹³-2x¹²-x¹¹+2x¹⁰=0

x¹⁰(x³-2x²-x+2)=0

x¹⁰(x+1)(x-2)(x-1)=0

x¹⁰=0    ∨   x+1=0    ∨    x-2=0   ∨   x-1=0

x=0             x= - 1             x= 2          x= 1

Search results for There were 35 bunches of roses and tulips. Each brunch at 12 of the same flowers. There were seven more bunch
KIM [24]
If it is supposed to say <span>seven more bunches of tulips than roses,  that would mean, if there are 35 bunches in all, and if each bunch had 12 of the same flowers.... that must mean each bunch had 12 flowers so, 12*1/2/35.  35/1/2 would be 35/0.5 that would equal... 17.5. so, 12*17.5= 210. if there was seven more added, than, 7/2= 3.5 and 12*3.5= 42. 210+42=252.

That means there are 252 tulips, i might be wrong (i probably am), i am just going by logic, lol
