Step-by-step explanation:
90 - 60 = 30
30 - 18 = 12
X=12
Answer:
the total surface area would be 233^2 im pretty sure (im not 100% sure) because the you do the lateral surface area add the top surface area add the bottom surface area so im pretty sure the answer would be 233cm^2 (^2 means squared)
Answer:
$1.10
Step-by-step explanation:
The cost of one meter of fabric is $1.20.
Given that 1 ft = 0.305 meters
Hence, 1 meter = 
ft = 3.278 ft
So, the cost of 3.278 ft of fabric is $1.20
As Sarah needs 3 feet of fabric for her project, then it will cost 
Dollars (Approximate)

Answer:
8x2y - 6x2 - 8xy2 - y2
Step-by-step explanation:
Equation at the end of step 1 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)
Step 2 :
Equation at the end of step 2 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)
Step 3 :
Equation at the end of step 3 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)
Step 4 :
Equation at the end of step 4 :
(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)
Step 5 :
Equation at the end of step 5 :
(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 6 :
Equation at the end of step 6 :
((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 7 :
Final result :
8x2y - 6x2 - 8xy2 - y2
This expression simplified would be 9a-18b-11
