Answer:
ANS i don't understand o ls write full question..
There are 52 weeks in a year. In order to figure out how much you have to save each week to save a total of $2000, you have to divide $2000 by 52.
2000÷52= 38.462
So to save $2000 you would have to set aside about $38.50 each week.
X^2 x 8x -3x^2 +5 x 8x -5 x 3
8x^3 -3x^2 +40x -15
