Fill the gap if x×y x - 15 120 a a 12 c 33
y - 5 40 3 6 b a d
​

x - 15 120 9 18 12 33

y - 5 40 3 6 4 11

Step-by-step explanation:

x - 15 120 a a 12 33

y - 5 40 3 6 b d

x = 3y

When y = 5

x = 3y

x = 3 * 5

x = 15

When y = 40

x = 3y

x = 3 * 40

x = 120

When y = 3

x = 3y

x = 3 * 3

x = 9

When y = 6

x = 3y

x = 3 * 6

x = 18

When x = 12

x = 3y

12 = 3y

y = 12/3

y = 4

When x = 33

x = 3y

33 = 3y

y = 33/3

y = 11

it should be a and d. lmk if i'm wrong xd

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
