The length of a rectangle six times it’s width is the perimeter of the rectangle is 70 feet find its area

A = 150 feet

Step-by-step explanation:

perimeter of rectangle = 2w + 2l

l = 6w

70 = 2w + 2(6w)

70 = 2w + 12w

70 = 14w

w = 70/14

w = 5

l = 6 x 5 = 30

area = l x w

A= 30 x 5 = 150 feet

don't forget the units

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
