What is the solution set to the inequality 5(x - 2)(x + 4) > 0? O {x| x>-4 and x <2}
O {x| X <-4 or x> 2}
O {x| X <-2 or x>4}
O {xl >-2 or x <4}

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

That they are numbers and related to each other.
