34 because 8.50 multiplied by 4 is 34
22 × 35= 770
770 × 18= 13,860
13,860 × 105= 1,455,300
1,455,300 ÷ 2,000= 727.65
727.65 rounded to the nearest whole ton is 728

Answer:
the question is not clear enough
Step-by-step explanation:
1) Perfect squares:
a²+14a+49 = (a+7)²
a²+26a+169 =(a+13)²
2) Differences of squares
a²-36 = (a-6)(a+6)
w²-121 = (w-11)(ww+11)
