How to solve for x in a right triangle To find the value of x, use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. In other words, if you know the lengths of two sides of a right triangle, you can find the length of the third side by using this equation: a^2 + b^2 = c^2. To solve for x, plug in the known values for a and b, and then solve for c. For example, if you know that a = 3 and b = 4, then you can solve for c like this: 3^2 + 4^2 = c^2 9 + 16 = c^2 25 = c^2 c = 5 Therefore, in this example, x = 5.

There are a lot of different math solvers out there with different features. Some have advanced graphing capabilities, while others focus on providing step-by-step solutions. However, one feature that is essential for any math solver is the ability to show work. This is vital for understanding how the solver arrived at its answer and for checking the work for errors. A math solver with work is an invaluable tool for students and teachers alike.

A differential equation is an equation that relates a function with one or more of its derivatives. In order to solve a differential equation, we must first find the general solution, which is a function that satisfies the equation for all values of the variable. The general solution will usually contain one or more arbitrary constants, which can be determined by using boundary conditions. A boundary condition is a condition that must be satisfied by the solution at a particular point. Once we have found the general solution and determined the values of the arbitrary constants, we can substitute these values back into the solution to get the particular solution. Differential equations are used in many different areas of science, such as physics, engineering, and economics. In each case, they can help us to model and understand complicated phenomena.

Word math problems can be tricky, but there are a few tips that can help you solve them more quickly and easily. First, read the problem carefully and identify the key information. Then, determine what operation you need to perform in order to solve the problem. Next, write out the equation using numbers and symbols. Finally, solve the equation and check your work to make sure you've found the correct answer. By following these steps, you can approach word math problems with confidence and avoid making common mistakes. With a little practice, you'll be solving them like a pro in no time!

Let's say you're a cashier and need to figure out how much change to give someone from a $20 bill. You would take the bill and subtract it from 20, which would give you the amount of change owed. So, if someone gave you a $20 bill, you would give them back $16 in change since 20-4 equals 16. You can use this same method to solve problems with larger numbers as well. For example, if someone gave you a $50 bill, you would take the bill and subtract it from 50, which would give you the amount of change owed. So, if someone gave you a $50 bill, you would give them back $40 in change since 50-10 equals 40. As you can see, this method is simple yet effective when trying to figure out how much change to give someone. Give it a try next time you're stuck on a math problem!

Very useful app. It is very accurate when it comes to manual calculating but a little bit less accurate when it comes to camera scanning. But overall, it is a very great app and I highly recommend this app to all students.

This app is wonderfully the reason I don't fall all of my school work lol. No but far it's God sent, but sometimes you have to look because it gets it wrong because you didn't take the picture clear enough. So just make sure the picture is taken well and you'll be all good
