Y = 47.3 + 0.78x
If it is expected that there will be 17 inches of rain, then the number of bushels of wheat per acre is 47.3 + 0.78(17) = 47.3 + 13.26 = 60.56
Answer:
A
Step-by-step explanation:
A trinomial can be factored into two binomials, when the discriminant of the trinomial is greater than or equal to 0.
The discriminant for trinomial is he expression
Check all options:
A.
then
Thus,
B.
so this trinomial cannot be factored.
C.
so this trinomial cannot be factored.
D.
so this trinomial cannot be factored.
