Answer:
-7w
Step-by-step explanation:
-2w - 5w are like terms because they both have "w"
-2 - 5 = -7
The next number is 27 because it is decreasing by 9 each time
Expand it so the expression would equal
5x^2+11x+2=-1
move the negative one over by adding one to both sides
5x^2+11x+3=0
then do the quadratic formula
x=-b+/- (√(b^2-4ac))/2a
where b = 11 a=5 and c=3
