    Study Notes

    Algebra and Equations

    • Quadratic equation: x² - 9x + 18 = 0, roots are x = 3 and x = 6.
    • Average speed calculated using the formula for two speeds: (2 * Speed1 * Speed2) / (Speed1 + Speed2) results in an average speed of 400 miles/hour for a jet returning from City 2 to City 1.
    • Composition of functions: g(f(x)) results in 14x² + 3 for f(x) = 7x² - 3 and g(y) = 2y + 9.

    Quantitative Comparisons

    • Comparison of x (Quantity A) and 2x (Quantity B) shows that the relationship cannot be determined as x could be positive or negative.
    • Problem involving prime numbers states that if one less than three-eighths of a positive integer n equals the third prime (5), then n is 16.

    Solving Equations

    • Equation (x - 5)² = 900 indicates potential solutions: x = 35 or x = -25.
    • System of equations: Solving 3x + y = 13 and x - 2y = -12 yields value x = 2.
    • Expression manipulation reveals if 6h - 2g = 4g + 3h, then h = 2g.

    Factorization and Age Problems

    • The factorization of 25x² - 36y² results in (5x - 6y)(5x + 6y).
    • Age relationships indicate Sally (younger than Abby) and Daisy (older than Tracy) leads to a conclusion that Daisy's age is greater than Sally's.

    Exponential and Quantitative Comparisons

    • Comparing powers: Quantity A (4³) is less than Quantity B (3⁴).
    • Given relationships a = 1/3b and b = 4c, the expression a - b + c simplifies to -5/3c.

    Toys Production Problem

    • Work rate problem: Bob and Bill together can build 4k toys in 8 hours based on their respective speeds (k toys in 6 hours for Bill and k in 3 hours for Bob).

    Additional Challenges

    • Finding the next consecutive odd integer after the sum of two consecutive odd integers (sum = 32) leads to identifying the next integer as 19.
    • The equation x² + kx - 12 = 0 having one root as 3 determines that k > -1.

    Exponents and Digits

    • The units digit of 2^102 parallels observing the cycle of units digits in powers of 2, confirming it is 4.
    • The relationship between (x + y)³ and x³ + y³ indicates expansion to include terms related to both x and y if neither is equal to 0.
