All and how do u do it. step by step. need to learn

Asking someone else to start from scratch and explain everything when you yourself have not done or shared anything is a BIG and unrealistic order.
Could you not at least share your thoughts as you read through each of the four problems?

Let's take a look at the 2nd problem (#17):

"Three times the sum of two times m and 5  is 4 less than 8 times m to the 2nd power."  You must be able to translate a word problem like this one into algebraic symbols.

3(2m+5) = 8m^2 -4   (This is the desired answer)

Then 6m + 15 = 8m^2 - 4   => 8m^2 - 6m - 4 - 15 = 0 (after rearrangement)

Then 8m^2 - 6m - 19       (you are not required to solve this)

Please choose another problem from your list and do and share all you can about your efforts to solve it.
