14 = 31.7 - 3x
-17.7 = -3x
x = 5.9
If she can make 1 batch with 1/2 then with 3/2 she can make 3 batches
3x^2+21x+6=3(3x^2+7x+2)=3(3x^2+6x+x+2)=3[3x(x+2)+(x+2)]=3(3x+1)(x+2)
The answer would be 249 with a remainder of 1
You would first put the 2 over the 4, as 2 times 2 is 4. Bring the 9 down. 2 goes into 9 about 4 times, but it has the remainder of 1. You bring the other 9 down, and now it says 19. 2 x 9 equals 18, so you put the 9 on top and there you have 249 with the remainder of 1.
