Answer :Opposite numbers are the same distance from 0 on the number line, but in opposite directions. Steps I would follow:
first, check the directions to make sure they are opposite,
then read the digits, or count the tick marks or compare lengths with dividers or ruler or marks on a piece of paper to see if the distances are the same.

Answer:
25
Step-by-step explanation:
The factors of 15625 are = 5 * 5 * 5 * 5 * 5 * 5. =25 * 25 * 25 Þ the cube root of 15625 is 25.
Given:
Area of polygon = 484 cm²
apothem 12.1 cm
sides of length = 10 cm
no. of sides = x
Area of a regular polygon = 1/2 perimeter * apothem
484 cm² = 1/2 * (10cm * x) * 12.1cm
484 cm² = 6.05cm * 10cm * x
484 cm² = 60.5 cm² * x
484 cm² ÷ 60.5 cm² = x
8 = x
The polygon is an OCTAGON. It has 8 sides.
Perimeter = 10 cm * 8 sides = 80 cm
484cm² = 1/2 * 80cm * 12.1 cm
484cm² = 1/2 * 968 cm²
484 cm² = 484 cm²
The first one is a and the second one is b
