a rectangle with positive area has length represented by the expression 2x+5 and width represented by x - 4. write expressions in terms of x for the perimeter and area of the rectangle. give your answers in standard polynomial form and show your work.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
