Answer:
The answer to your question is: It could be letter A but power 5 is not necessary.
Step-by-step explanation:
Simplify like terms
1.- Remove parenthesis
(3m² + m - 5) + (3 - 6m² + 4m + 5m)
3m² + m - 5 + 3 - 6m² + 4m + 5m
2.- Group like terms
(3m² - 6m²) + (m + 4m + 5m) + (3 - 5)
3.- Simplify
- 3m² + 10m - 2
Answer:
n(A) + n(B) - n(AnB) = n(AUB)
12 + 7 - n(AnB) = 10
19 - n(AnB) = 10
19 - 10 = n(AnB)
n(AnB) = 9
Step-by-step explanation:
length =88cm
breadth=21cm
when it is rolled it becomes cylinder
having circumference 88cm
2πr=88cm
r=88×7/44
r=14
h=21
total surface area of the cylinder =2πr(r+h).
=2×22/7×14(14+21)
=3080cm²
Answer:
Step-by-step explanation:
7) The tangent angles are 90° each.
The angles of a quadrilateral add up to 360°, so ? = 360°-90°-90°-73° = 107°.
8) Solve this the same way as question 7). ? = 360°-90°-90°-57° = 123°.
Questions 9) and 10) are cut off, so I assume you don't need to know those.
