4x-20+2x+8=180
add like terms
6x+12=180
x=28
then substitute to get 92
£67.00 / 7= £9.57that’s how much cost the hat

Why?</h2>
When the egg hit the ground, the height will be equal to 0, so, from the given equation we need to find the roots or zeroes.
It's a quadratic function, we can find the roots using the quadratic equation:

So, from the given function we know that:

So, substituting we have:



So, since the time can not be a negative value, the correct option is:
6.18≈6.2 seconds
Hence, it takes 6.2 seconds to the egg to hit the ground.
Have a nice day!
