Answer:
multiply 9 from m and -3
9m - 27 + 3m = 7m + 43
12m - 27 = 7m + 43
12m - 7m = 43+ 27
5m = 70 cut 70 by 5 in 14 times [ 14 x 5= 70 ]
m = 14 answer ❤️❤️ it is 100% correct now!

Answer:
C. x =3
Step-by-step explanation:
Extraneous solution is that root of a transformed equation that doesn't satisfy the equation in it's original form because it was excluded from the domain of the original equation.
Let's solve the equation first

Hence, we can conclude that x=3 is an extraneous solution of the equation ..
Answer:
431.775 ft
Step-by-step explanation:
So basically we should first find the area of the rectangles which is 28 ft * 15 ft, which you get 420. Next for the semicircle, the diameter is 15 but we need the radius so you divide that by 2 to get 7.5 as the radius. Then u multiply 7.5 * π, or 3.14 to get 23.55. But since its a semicircle, or half a circle we divide 23.55 by 2 which is 11.775. Then we just add the results which is 420 ft and 11.755 ft to get a total area of 431.775 ft.
