To change the equation, you'd have to take the square root of both sides. When you do this, x^2 cancels out leaving you with x = sqrt(y)
If you need help on the other ones, all you have to do is solve for x by using either addition/subtraction or dividing/multiplying.
Gaining stream describes a stream which receives water through the inflow of groundwater through the stream bed.
Groundwater that enters a gaining stream is coming from a saturated zone. Gaining stream channels are typically at or below the water table level. When the water table crosses the land surface over a large, relatively flat area, bodies of water and marshes are formed.
The channels of gaining streams are usually at or below the level of the water table. Bodies of water and marshes form when the water table intersects the land surface over a broad, fairly flat area.
"Gaining stream," which typically draws water from the earth. The term "losing streams" refers to streams that leak water into the earth from the streambed. Rivers can grow and shrink in different places; they can grow at one point in the year and shrink at another. Additionally, even a stream that is growing will be losing some water, as the yellow arrow illustrates, and vice versa.
