Factor this trinomial completely -10x^2+36x=36 that 2 is on top of the x

X= 3.7

Step-by-step explanation: -10^2=100 and then you add the 36 which you’ll then be left with 36x=136 then you’ll divide and be left with 3.7

The ratio of white:milk:dark is  9:8:4

Explantion:

Let w represent white chocolate , m represent milk chocolate and  d represent dark chocolate

The ratio of white to not white is 3:4

Here not white means , it can be milk or dark chocolate

Then

w : (m+d) = 3:4 -----------------------------(1)

The ratio of not dark to dark is 17:4.

Again not dark means , it will be white or milk chocolate

Then,

(w+m) : d = 17:4  -----------------------------(2)

Representing (1) in fractions

4w = 3(m+d)

4w = 3m +3d

4w -3m =3d------------------------------(3)

 Representing (2) in fractions

4(w+m) = 17d

4w +4m = 17d---------------------------(4)

Subtracting (3) from (4)

4w +4m = 17d

4w -3m = 3d

(-)

-------------------------------

7m = 14d

-------------------------------

m:d = 2:1

Since w:(m+d)=3:4 let's make m:d a multiple of 4.

m:d = 8:4

w : (m+d) = 3:4 = 9:12

w:m:d = 9:8:4
