if you meant x^2+9x+20 then it is (x+4)(x+5) you know that because 4+5=9 and 4x5=20 using FOIL
total = 3000*(1-0.011)^10
1-0.011 = 0.989
total = 3000*(0.989)^10
0.989^10 = 0.895288314
3000* 0.895288314 = 2685.86
rounded to nearest whole number = 2686
there will be 2686 people
These cannot be solved.- 3 unknowns require 3 equations
If he plays 3 matches a week for 9 weeks, you have to multiply 3&9.
3*9=27
Daniel will have played 27 tennis matches by the end of the 9 weeks.
Hope this helps:)
When I do what the problem statement says, I get 47° for the left angle and 58° for the right one. They are not congruent.
