When simplifying algebraic fractions, first times all the components by the denominator (number on the bottom) of the first component. In this case, that is 3. x/3 times 3 = x and x/4 time 3 = 3x/4. This ...

4x +7 = 13 4x = 6 x=6/4 x=3/2

To calculate the perimeter (the length of the outside edge) of a square, you must add up the length of each side. Here, we have been given the area of the square. The area of a square is calculated by squ...

We first see that we are asked to solve the equation in terms of y. We can see that y = 2^x, and there is also a 2^x in the equation, meaning we can instantly change that to y. However, there is also a 4^...
