X - 2y = 4
3x +2y = 4

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation

a≈380.13mi² would be your answer if the radius was 11 miles
