Answer:Answer is option C : [ + 3x + 3 ] =0
Note: None of options matches with given question.
instead of "-3" , there should be "-".
Step-by-step explanation:
instead of "-3" , there should be "".
Here, First thing you have to observe the nature of roots.
∴ x = -+i and x = --
∴ [ x+(-i) ][ x+(+i) ]=0
∴ [ + x(+i)+ x(-i) + (-i)(+i) ]=0
∴ [ + x + ix + x - ix + (3-i)(3+i) ] =0
∴ [ + 3x + (-i)(+i) ] =0
∴ [ + 3x + - (i)(i) ] =0
∴ [ + 3x + - () ] =0
∴ [ + 3x + + () ] =0
∴ [ + 3x + ] =0
∴ [ + 3x + 3 ] =0
Thus, Answer is option C : <em>[ + 3x + 3 ] =0 </em>
Answer:
Step-by-step explanation:It must be an equal ratio- 2:3:7 = n:n:112
Now, to find the other numbers (n) in the ratio, we have to find the relationship between the two proportions.
To get from 7 to 112, we must multiply by 16. This is the relationship.
So, we must multiply both, the walnut and raisin cookies by 16 also.
2 x 16 = 32 = Raisin
3 x 16 = 48 = Walnut
Already known: 112 = Pinwheel
Now that we have all the data, we can make the ratio.
Raisin : Walnut : Pinwheel
32 : 48 : 112
Hope this helps! :)
