If r=-4, then r - 3 is 61. 3. Replacing the variable by a given number value is what we call substitution. 4. When a = 2 and b = 9, then 15(a + b)2 is 1815. 5. x2 - 5x2 = -3x2 for any value of x. 6. 9a + 3 is greater than 3(3a + 1) if a = 5. If a = 3 and b = -2, then 15a - 24b - 15 is less than 15a + 24b + 15. 8. (5x2 - 7x +8 ) + (x2 + 3x - 12) = 6x2 - 4x - 4 for any value of x. 9. When t = 2, then 4t3 + 10 is 42. 10. (a2-5a) - (a2 - 4a) = -9a for any value of a. N . - =​
