360.
A general rule of thumb when dealing with questions like these is using the following equation:
(number of numbers) x (mean) = sum of numbers
Proof/Example: 7, 10, 13
There are 3 numbers here and the mean is 10. Multiply them together and you will get 30, just as you will get 30 from adding them together.
In this case, there are 4 numbers and the mean is 90, so 4 x 90 = 360.
Answer:
-12p^2 - 12pq + 2p -3q^2 + q
So this is a BIDMAS question so first you do what’s in the brackets so you have (1-9x1-4) and you have to do the multiplication first out of that to get (1-9-4) which is -12 so then you have overall 36 / -12 + 1 + 2 so you have to do the division first so do 36/-12 to get -3 and you have -3 + 1 + 2 which is 0 so your answer is 0.
