X is used in math to represent an unknown or missing value. X is used to create expressions and equations to solve for the value. What does an X symbolize? An X symbolizes a cross sign, which ...
rkm409946. The expression (4x + 7) (5x - 20) simplifies to 20x^2 - 45x - 140. To find the value of x in the given expression, we need to simplify the expression by using the distributive property. Distribute the 5 to both terms inside the parentheses: 5 * x = 5x and 5 * -4 = -20. Now, the expression becomes (4x + 7) (5x - 20).

Solutions. 1. The mean or average value of the number of chocolates in the boxes is given by the sum of the total number of chocolates in the boxes divided by the number of boxes. This is ...
Exterior Angle sum property of the triangle states that the Sum of all exterior angles of the triangle is 360. Given: Two exterior angles measure of 130 and 134 degrees. To find: The value of x is. So, 130 + 134 + x = 360 . 264 + x = 360. x = 360 - 264 . x = 96. Using Exterior Angle sum property of the triangle, The value of x will be 96 degrees.
Before learning how to take derivative of the absolute value function, we first need to understand the signum function.Such function, denoted by {eq}\textrm{sgn}~(x), {/eq} associates each real ...
Absolute Value Function. The absolute value of a number is the distance between that number and zero. For instance, the absolute value of 7 is 7, the absolute value of -5 is 5, and the absolute ...
The function f (x) = 1 x is the most basic example of a rational function in mathematics. A rational function is a function that can be expressed as a fraction with a polynomial in the numerator ...
Let's work through an example to find the maximum value of a function: f (x) = − 3 x 2 + 6 x + 4. Because we are given the equation in the general form, we can find the critical point by first ...
