WebAnswer (1 of 3): x squared = x^2 = x * x { Note: x * x is more correctly written xx or x^2 } If you have a value for x, substitute it into x^2 and multiply out. Examples: x = 3 ==> x^2 = 3 * 3 = 9 x = a + b ==> x^2 = (a + b)^2 = a^2 + 2 ab + b^2 x … WebThe mathematical statement x . 3, read as "x is less than 3," indicates that the variable x can be any number less than (or to the left of) 3. ...

Thus, at x = -3 , p (x) will become zero. ie, => p (-3) = 0 => (k-1) (-3)^2 + k (-3) + 1 = 0 => (k-1) (9) -3k + 1 = 0 => 9k - 9 - 3k + 1 = 0 => 6k - 8 = 0 => 6k = 8 => k = 8/6 => k = 4/3 Hence, Web31 okt. 2024 · (1) x^2 > 9 --> x < − 3 or x > 3 as given that x < 0 then we have that x < − 3. Sufficient. (2) x^3 < –9 --> if x = − 3 ( x 3 = − 27 < − 9) then the answer will be NO (as x equals to -3 and is not less than -3) but if x = − 4 ( x 3 = − 64 < − 9) then the answer will be YES. Not sufficient. Answer: A. D avigutman Tutor Joined: 17 Jul 2024 ford aod transmission pan with drain plug
