Don't do it just for the points i'm begging find the value of this integer expression: -2(+3+-4+-8++7) show all steps! thx

Just add the numbers inside the ‘house’. For example, +3+-4+-8++7
7+3=10
10+-4= +6
6+-8= -2

Now, add “-2+-2” which = -4

4

Step-by-step explanation:

-2x3= -6

-2x-4= 8

-2x-8= 16

-2x7= -14

then -6+-14= -20

and 8+16= 24

24 - 20 = 4

You verify your answer by using the F.O.I.L. method. First Outside Inside Last. This shows that (x+5) & (x-8) is not the correct factors for 2x-2x-30 or x2-2x-30. Either way, the factors are not right for either of those equations. Hope my answer helps you
