3x + x + 5 – 2x if he simplifies the expression, which statements are true about the parts of the simplified expression? check all that apply.

3x+x+5-2x
U can check of you can't solve for x because there aren't any equal signs 
there will be only one x left 

A) 144.44 sq inches i believe

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
