Section 2: Algebra and Equations

This section explores algebraic concepts, including solving equations and working with variables.

Question 11: Solve for x: x + 7 = 12

Answer: x = 12 - 7 = 5

Question 12: Solve for y: 2y - 5 = 9

Answer: 2y = 9 + 5 = 14; y = 14 / 2 = 7

Question 13: Solve for z: z/3 + 2 = 8

Answer: z/3 = 8 - 2 = 6; z = 6 * 3 = 18

Question 14: Simplify the expression: 3x + 2x - x

Answer: 4x

Question 15: Expand the expression: 2(x + 4)

Answer: 2x + 8

Question 16: Solve the system of equations: x + y = 5 x - y = 1

Answer: Add the two equations: 2x = 6; x = 3. Substitute x = 3 into the first equation: 3 + y = 5; y = 2. Solution: x = 3, y = 2.

Question 17: What is the slope of the line represented by the equation y = 2x + 3?

Answer: The slope is 2. (This is in the form y = mx + b, where m is the slope)

Question 18: Find the roots of the quadratic equation: x² - 5x + 6 = 0

Answer: (x - 2)(x - 3) = 0; x = 2 or x = 3

Question 19: Simplify the expression: (x³)(x²)

Answer: x⁵ (Add the exponents when multiplying terms with the same base)

Question 20: If a = 3 and b = 4, what is the value of a² + b²?

Answer: 3² + 4² = 9 + 16 = 25

Section 3: Geometry and Measurement

This section focuses on geometric shapes, their properties, and measurements.

Question 21: What is the area of a rectangle with length 10 cm and width 5 cm?

Answer: Area = length * width = 10 cm * 5 cm = 50 cm²

Question 22: What is the perimeter of a square with side length 7 cm?

Answer: Perimeter = 4 * side length = 4 * 7 cm = 28 cm

Question 23: What is the area of a triangle with base 8 cm and height 6 cm?

Answer: Area = (1/2) * base * height = (1/2) * 8 cm * 6 cm = 24 cm²
