-3x^2+10x-3
This is of the form ax^2+bx+c. We need to find two values, j and k, such that:
jk=ac=9 and j+k=b=10, so j and k must be 1 and 9.
Now replace bx with jx and kx in the original equation...
-3x^2+x+9x-3 now factor 1st and 2nd pair of terms
-x(3x-1)+3(3x-1)
(-x+3)(3x-1) or equivalently...
-(x-3)(3x-1) or as they put it:
-(3x-1)(x-3)
Answer:
65
Step-by-step explanation:
35+40+27+42+45+50=249 249+65=315 315/7=45
<span>The temperature of water in a glass if room temperature is 21 degrees Celsius if a glass is standing one in that room, because room temperature is commonly given as 20 to 22 degrees Celsius, however, if the air in the room goes through temperature variations,then a body of water will heat up or cool down,then the temperature of the water in the glass tends to average out those temperature variations.</span>
Answer:
The Answer Is B
Step-by-step explanation:
-4/5 = -1 (Rounded)
3/5 = 1/2 (Rounded)
-6/7 = -1 (Rounded)
5/6 = 1 (Rounded)
If your looking for the whole thing it would be:
(-1)[1/2](-1)(1) = x
