What is the perimeter of a square that has and area equal to 64??

32

Step-by-step explanation:

The perimeter is the sum of the 4 sides of the square

Given area is 64 and

area = s² ← s is the length of the side, thus

s² = 64 ( take the square root of both sides )

s = = 8, thus

perimeter = 8 + 8 + 8 + 8 = 4 × 8 = 32

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
