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.
202 - 18 = 184 (the length is 9ft longer than the width, and you double the length to find the perimeter, so you double the 9)
184 ÷ 4 = 46 (4 being the 4 sides of the rectangle)
width = 46
length = 46 + 9 = 55
55 x 46 = 2530
Area = 2530ft²
Answer:
is this the only thing it shows on the screen or does it have anything else that goes with the question?
Step-by-step explanation:
I'm going to go with C.
The inequality isn't greater than OR EQUAL TO which marks out B and D.
The inequality is showing that it is greater than -21 meaning that the shaded area should be towards the positive which in turn marks out A.
