3x - 14 = x + 2
- x    - x
2x - 14 = 2
    + 14 + 14
       2x = 16
      2 2
   x = 8

4y - 7 = y + 11
- y    - y
3y - 7 = 11
    + 7 + 7
      3x = 18
   3 3
   x = 6
(x, y) = (8, 6)

The answer is D.

If the length of the side of a square is doubled, what is the ratio of the areas of the original square to the area of the new s

7nadin3 [17]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Let 's' be the side of the original square

the length of the side of a square is doubled, so the length of the new square is 2s

Area of the original square with side length 's' is $s^2$

Area of the new square with side length '2s' is $(2s)^2=4s^2$

Area of the new square is 4 times the area of the original square

ratio of the areas of the original square to the area of the new square

$\frac{s^2}{4s^2} =\frac{1}{4}$
