Answer:
12x-940
Step-by-step explanation:
Answer:
x = -2
Step-by-step explanation:
Step 1: Subtract 5x from both sides.
12x+11−5x=5x−3−5x
7x+11=−3
Step 2: Subtract 11 from both sides.
7x+11−11=−3−11
7x=−14
Step 3: Divide both sides by 7.
7x -14
7 = 7
x=−2
Answer: 8th degree
Step-by-step explanation:
It is a polynomial of the 8th degree since 8 is the highest exponent
Answer:
Surface area of triangular prism is:
Surface area = 2376ft
Step-by-step explanation:
A triangular prism is the one which has 3 rectangular sides and 2 triangular sides. To find the surface area of a triangular prism, we have to find the surface area of 3 rectangular side and 2 triangular sides and add them up
Surface Area (rectangle) = Length · Width
Surface Area (triangle) = (1/2)(Base)(Height)
Rectangular side 1:
Length = 40 ft
Width = 24 ft
Surface Area = 40 · 24
Surface Area = 960ft
Rectangular side 2:
Length = 40 ft
Width = 15 ft
Surface Area = 40 · 15
Surface Area = 600ft
Rectangular side 3:
Length = 40 ft
Width = 15 ft
Surface Area = 40 · 15
Surface Area = 600ft
Triangular side 1:
Base = 24 ft
height = 9 ft
Surface Area = (1/2)(24)(9)
Surface Area = 108ft
Triangular side 2:
Base = 24 ft
height = 9 ft
Surface Area = (1/2)(24)(9)
Surface Area = 108ft
SURFACE AREA OF TRIANGULAR PRISM:
Add all surface areas found above
Surface area = 960 + 600 + 600 + 108 + 108
Surface area = 2376ft
266.4 - 8.5 - 24 will give you the answer of 233.9
