Help me please I need help
exis [7]
Since you know a = 5√2, start by plugging that into your other equation, 2a = √2x to get an equation where x is the only variable you need to solve for:
2a =  \sqrt{2x} \\
2(5 \sqrt{2} ) =  \sqrt{2x}\\
10 \sqrt{2} = \sqrt{2x}

There are two ways of solving for x:
1) Remember when you simplify radicals, you break what's underneath the radical into smaller factors. If a factor repeats under the square root, you can take two of them out and put one of them outside the radical sign (see picture for example). For this problem, you would be doing the reverse of simplifying. You have a 10 on the outside on the left of the equal sign, but a 2 underneath on both sides. If the 10 was taken out, that means there had to be two 10's underneath the radical to begin with. Those two tens would have been multiplied since they are factors, so 10 x 10 = 100. That means x = 100. 

2) Solve it algebraically. Square both sides, simplify, then divide by 2:
10 \sqrt{2} = \sqrt{2x}\\
(10 \sqrt{2})^{2} = ( \sqrt{2x})^{2}\\
100*2 = 2x\\
200 = 2x\\
x = 100\\

Answer: x = 100

Alenkinab [10]

Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage. The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft)
