Step-by-step explanation:
3x²+11x-4
when splitting the middle term
it becomes
3x²+12x-1x-4
=3x(x+4)-1(x+4)
(3x-1)(x+4)
either 3x-1=0 then x=1/3
or x+4=0 then x= -4
m=1/3
n=-4
therefore
value of m divided n plus n dividedm=1.25

-120 loves of bread were sold in 4 hours.
-40 loves of bread wereleft to sale.
Step-by-step explanation:
To determine the amount of loves of bead that were sold in 4 hours, you have to mutiply the amount of loves sold each hour for 4:
30*4=120
This means that 120 loves of bread were sold in 4 hours.
Now, to determine the amount of loves of bread left to sale, you have to find the amount of loves produced on the two batches of bread by multiplying the amount produce in each batch for 2:
80*2=160
Finally, you have to subtract the amount of loves sold in 4 hours from the amount produced in two batches:
160-120=40
According to this, 40 loves of bread were left to sale.
