What are the coordinates of the point (-8,5) if it is reflected across the x-axis? a. (8,5)
b. (8, -5)
c. (-8,5)
D. (-8,-5)

I’ll mark branliest

D:(-8,-5)

Step-by-step explanation:

It is already negative and if plotted the coordinates then reflected, it will give this answer

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
