Answer:
165
Step-by-step explanation: find the area or the field A=r^2
the radius is 290/2=145ft
A=145* 145* 3.14= 66018.5 sqr ft
66018.5 / 400= 165
2.8- 4.4n- 2n + 7 = -6.4n + 9.8
Step-by-step explanation:
combined like term:
-4.4n - 2n = -6.4n
2.8 + 7 = 9.8
so all you do is combined together and got -6.4n + 9.8
B
-11(over)10-4x^2
-7 > v OR vice-versa [v < -7]
Combine like-terms [-5v > 35], then divide by -5.
NOTE: Since you are dividing by a negative, reverse the sign.
