Answer:
270 ft^2
Step-by-step explanation:
find the area of each side
top: 13x7=91
triangle shaped sides(both together): 12x5=60
tiny vertical side: 7x5=35
bottom: 12x7=84
add them all together to get the total surface area is 270ft^2
Hope this helps! :)
Answer:
some circles are similar to a circle with a radius unit of 1
Step-by-step explanation:
(x-a)²
8x + 20 - 11 = 4x - 3
8x + 9 = 4x - 3
8x + 12 = 4x
12 = -4x
-3 = x
X = -3
