The equations of four lines are given. Identify which lines are parallel. Line 1: y=−3/4x−6 Line 2: y−7=−4(x+9) Line 3: y=−2x+6 Line 4: x+4/3y=−5

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

i honestly dont know

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
