Which expression is already in its simplified form? a.) 3t+ (s +t)
b.) 6h + 2(h+ 3k)
c.) 5m + 7mn + 4n
d.) 8 + y3 - 5z2 + 2y3

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.
