180=4x
180/4= 45=x
x+81
45+81=126
What I believe they are asking is to find which of those is the simplified quadratic formula. The quadratic formula is -b (plus or minus) (√b²-4ac) all divided by 2a.

Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the volume of the silo

so
we have
---> the radius is half the diameter
substitute
Remember that
The silo is approximately 85% full
so
The volume of grain in the silo is
step 2
Find the number of bags of grain
Divide the volume of grain in the silo by the volume of one sack
