Answer:

42

Explanation:

If the scale factor is 2/7 divide 12 by 2 which is 6. 6 is 1/7 and if Figure a is 7/7

multiply 6 by 7 to get x. That would be 42.

Answer:

42

Explanation:

Since the scale factor is
(2)/(7) , we know that the bigger shape went to the smaller shape.

If we know that the smaller shape's side, 12, is
(2)/(7) of the bigger one, we can make the equation

(2)/(7)x = 12 .

To solve for x, we can divide both sides by
(2)/(7) .

x = 12/{(2)/(7)}

We can multiply by the reciprocal:

$(12)/(1) \cdot (7)/(2) = (84)/(2) = 42$

Hope this helped!
