Since x is the x-intercepts, that means x'=x" =6 or in other word the discriminante ( Δ = b² 4ac) =0. Answer is A
I think that it is C: PQR~XY by AA because there are only two angles that you are given ;the boxes represent 90, so each box has 90 and 62.
Total number of squares = 60 + 80 + 110 + 115 + 95 + 40 = 500
1000/500 = 2 so each little square represents 2 people
60 x 2 as there’s 60 squares from 6-10 so answer is 120
