(ok i need with this question ! )

wyoming is an approximately square-shaped state. the area of wyoming is 97,818 square miles. to the nearest mile, how long is one side of wyoming? a) 48,909 miles b) 24,445 miles c) 12,226 miles d) 313 miles

area of a square is L×W=97,818. 313×313=97,818

D) 313 miles

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
