Arectangle has an area of 1050 square feet. its width is eight feet less than twice the length. find the measures of the length and width of the rectangle.

Step-by-step explanation:

If L represents the length, then the width is (2L-8) and the area is ...

  A = LW

  1050 = L(2L-8)

  525 = L(L-4) . . . . . divide by 2

Completing the square, we have ...

  525 +4 = L² -4L +4 . . . . . add the square of half the L coefficient

  529 = (L -2)² . . . .simplify

  ±23 = L -2 . . . . . . take the square root

  L = 25 . . . . . . . the negative root doesn't work in this scenario

  (2L-8) = 42 . . . width

The length is 25 feet; the width is 42 feet.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
