Section 1: Multiple Choice Questions 1. What is the value of x in the equation 3x + 5 = 23? A) 4 B) 6 C) 7 D) 8 2. What is the slope of the line passing through the points (2, 3) and (5, 9)? A) 2 B) 3 C) 4 D) 6 3. Which of the following is NOT a type of triangle? A) Equilateral B) Isosceles C) Scalene D) Quadrilateral 4. What is the value of y in the equation 2y - 4 = 10? A) 3 B) 6 C) 7 D) 8 5. What is the value of x in the equation 2x + 3 = 11? A) 3 B) 4 C) 5 D) 6 Section 2: Short Answer Questions 6. Define a prime number. 7. What is the formula for calculating the area of a triangle? 8. Write down the first five terms of the Fibonacci sequence. 9. What is the Pythagorean Theorem? 10. What is the formula for calculating the circumference of a circle? Answers: 1. B) 6. Explanation: Subtracting 5 from both sides of the equation gives 3x = 18. Dividing both sides by 3 gives x = 6. 2. D) 6. Explanation: The slope of a line passing through two points (x1, y1) and (x2, y2) is given by (y2 - y1) / (x2 - x1). Plugging in the values, we get (9 - 3) / (5 - 2) = 6/3 = 2. 3. D) Quadrilateral. Explanation: A quadrilateral is a four-sided polygon, while a triangle is a three-sided polygon. 4. C) 7. Explanation: Adding 4 to both sides of the equation gives 2y = 14. Dividing both sides by 2 gives y = 7. 5. A) 3. Explanation: Subtracting 3 from both sides of the equation gives 2x = 8. Dividing both sides by 2 gives x = 4. 6. A prime number is a positive integer that has no positive integer divisors other than 1 and itself. 7. The formula for calculating the area of a triangle is A = (1/2)bh, where b is the base of the triangle and h is its height. 8. The first five terms of the Fibonacci sequence are 0, 1, 1, 2, 3. 9. The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. 10. The formula for calculating the circumference of a circle is C = 2πr, where r is the radius of the circle and π is the mathematical constant pi (approximately equal to 3.14).

6. Draw an isosceles triangle. Draw all of its medians and altitudes. Write your observation about their points of concurrence.

2. The ratio of the perimeters of two similar triangles is 3/5. The scale factor is ________
