Answer:
20%
Step-by-step explanation:
- Loss=C.P-S.P
- Loss=10000-8000
- Loss=2000
- Loss%=loss/cp*100
- Loss%=2000/10000*100
- Loss%=20%
The answer would be A because A squared + B squared = C squared which is the hypotenuse.
Answer:
the first one but make sure to divide
Step-by-step explanation:
Answer:
x = 1/3, x = -1.
Step-by-step explanation:
2x(x + 2) + (x - 1)² = 2
Distribute the 2x into x + 2.
2x² + 4x + (x - 1)² = 2
Square (x - 1).
2x² + 4x + x² - x - x + 1 = 2
Combine terms.
2x² + x² + 4x - 2x + 1 = 2
Combine terms again.
3x² + 2x + 1 = 2
Subtract 2 from both sides.
3x² + 2x - 1 = 0
Factor.
(3x - 1)(x + 1) = 0.
Finding the x-values here is the same thing as finding the 0s, so set both of the expressions to 0.
3x - 1 = 0
Add 1 to both sides.
3x = 1
Divide by 3.
x = 1/3.
x + 1 = 0
Subtract 1 from both sides.
x = -1.
2x2 [4x 3x]
[12x 8x] I found the answer on the app math papa.
