Km pretty sure it’s C (the third one )

It's not C. Use the Geometric Mean for right triangles to solve. In our formula, our values will fit in like this: \frac{9}{x}=\frac{x}{9+7}. Simplifying we have \frac{9}{x}=\frac{x}{16}. Cross-multiply to get x^2=144. That means that x = 12. First choice above.

URGENT!! GIVING BRAINLIEST, 30 POINTS
Yakvenalex [24]

Answer:

No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.

Step-by-step explanation:

Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²

Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²

Total amount of paint needed: 522ft²-90ft²=432ft²

Amount of gallons needed remains the same

Hopefully this makes sense.
