Assignment 2 Solutions for Class 9 BBC Practice:

Question 1:
- To find the value of x, we can substitute the given values into the equation and solve for x.
- Given: 2x + 5 = 17
- Subtract 5 from both sides: 2x = 12
- Divide by 2: x = 6

Question 2:
- To calculate the area of the rectangle, we use the formula: Area = length x width
- Given: Length = 8 cm, Width = 5 cm
- Area = 8 cm x 5 cm = 40 cm^2

Question 3:
- To determine the missing angle in a triangle, we use the fact that the sum of all angles in a triangle is 180 degrees.
- Given: Angle A = 45 degrees, Angle B = 60 degrees
- Missing Angle C = 180 - (45 + 60) = 75 degrees

Question 4:
- To simplify the algebraic expression, we combine like terms and perform the operations indicated.
- Given: 3x + 2y - 4x + 5y
- Combine like terms: (3x - 4x) + (2y + 5y) = -x + 7y

Question 5:
- To solve the linear equation, we isolate the variable on one side of the equation.
- Given: 4(x - 3) = 24
- Distribute the 4: 4x - 12 = 24
- Add 12 to both sides: 4x = 36
- Divide by 4: x = 9
These solutions provide a step-by-step guide on how to approach and solve the given problems in the Class 9 BBC practice assignment 2.
