Define x♣y♣z as follows: x♣y♣z = x + y + z 3 Evaluate: 1000♣-2000♣1000

Step-by-step explanation:

hello :

x♣y♣z = x + y + z 3

Evaluate: 1000♣-2000♣1000

put x = 1000  and y = -2000  and z = 1000

1000♣-2000♣1000 = 1000-2000 +1000^3

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
