Arectangular garden has length and width as given by the expressions below. length: 4 − 7(3x + 4y) width: 3x(−2y) write a simplified expression for the perimeter of the rectangle.

Step-by-step explanation:

Perimeter is the sum of all the sides. Thus, in a rectangle there are 2 sides of length and 2 sided of width.

Thus, multiply boyh length and width by 2 and then add them. The equation will be as follows.

Perimeter of rectangular garden = 2 × length + 2 × width

                      = 2[4 − 7(3x + 4y)] + 2[3x(−2y)]

                      = 2[4 - 21x -28y] + 2[-6xy]

                      = 8 - 42x - 56y -12xy

Thus, we can conclude that the perimeter of given rectangular garden is (8 - 42x - 56y -12xy).

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
