A rectangular 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. ​

⇒ 8 −  ⇒ 42x −  ⇒ 56y −  ⇒ 12xy

Step-by-step explanation:

Im smart

8 − 42x − 56y − 12xy

Step-by-step explanation:

Yes.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
