Solve x2 equals 64?
x2 = 6482 = 64x = 8
X2 plus 7 equals 36?
if x2 + 7 = 37, then x2 = 29 and x = ±√29
Find a counterexample if x equals -5 then X2 equals 25?
In ordinary mathematics, assuming that x = X and that X2 denotes x2 or x-squared, there cannot be a counterexample since the statement is TRUE. However, there are two assumptions made that could be false and so could give rise to counterexamples. 1. x is not the same as X. If, for example X = 4x then X = -20 so that X2 = 400. 2a. X2 is not X2 but X times 2. In that case X2 = -10. 2b. X2 is x2 modulo 7, for example. Then X2 = 4.
X2 equals 11x - 10?
x2 = 11x - 10 ∴ x2 - 11x + 10 = 0 ∴ (x - 10)(x - 1) = 0 ∴ x ∈ {1, 10}
What is the derivative of 3cosx2?
I'm assuming your question reads "What is the derivative of 3cos(x2)?" You must use the Chain Rule. The derivative of cos(x2) equals -sin(x2) times the derivative of the inside (x2), which is 2x. So... d/dx[3cos(x2)] = -6xsin(x2)
What does x2 plus x2 equals?
x2 + x2 = 2x2
What is 9x20?
it is 180.
How many square ft is a 9x20 room?
To calculate the area of a room, multiply the length by the width. For a 9x20 room, the area is 9 feet multiplied by 20 feet, which equals 180 square feet. Thus, the room is 180 square feet in size.
