Answer:
24m-28
Step-by-step explanation:
4*6m=24m
-7*4=-28
24m -28
7/5 x 7/1 = 49/5 or 9 4/5
A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.
Area= i^2 + 4i
Area= length x width
Length (y)= i + 4
Width (i)=i
