Answer:
sorry I didn't know next time I tell you ok
If he is 4 now is in 10 years he will be 14 and if you multiply that by 2 you get 28 which means in 10 years Marie will be 28 so that means if you take away 10 the answer should be 18 but that isn't there but that's how I would work it out.
Neurofeedback involves trying to change brain wave activity.
<h3>Brain wave</h3>
The human brain is an intricate organ that baffles many scientists today. One design feature of the human brain is its ability to send signals in the form of brain waves when the mind is ar work or in a state of rest. These brain wave activity are braodly categorized into four types, namely;
- beta waves
- alpha waves
- theta waves
- delta waves
Neurofeedback thus occurs when an attempt is made to change from one of the above brain wave types to another.

Wind turbines generate electricity by following a simple principle. Moving wind transfers energy to the blades of the windmill, which results in spinning of the blades. These blades are connected to an internal shaft which also starts spinning. This spinning of the shaft generates electricity, which is further distributed to electrical substations to provide electricity to homes and businesses.
<h3>What is a wind turbine?</h3>
Wind turbines work by creating kinetic energy when the power of the wind makes their blades spin. This kinetic energy is converted into electrical energy.
Thus, the steps describing how a wind turbine functions are,
Step 1: Wind moves the blades of the turbine.
Step 2: Internal shaft spins
Step 3: Generator produces electricity
Step 4: Distribution lines carry electricity to substation
