Answer:
5140 and 3140
Step-by-step explanation:
Note there is a common difference d between consecutive terms in the sequence, that is
d = 140 - 40 = 240 - 140 = 340 - 240 = 100
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 40 and d = 100, thus
= 40 + (51 × 100) = 40 + 5100 = 5140
= 40 + (31 × 100) = 40 + 3100 = 3140
Is it inequality? If so, 5n<65 so n<13
-9(c+4)(c-4)
this is the answer to your question
Answer:
area = 228 m^2
Step-by-step explanation:
here's your solution
=> length = 20 m. , width = 12 m
=> Area of rectangle = length*width
=> Area of rectangle = 12*20
=> Area of rectangle = 240 m^2
now we need to find area of traingle
=> base = 4 m. , height = 6 m
=> area of traingle = 1/2*base*height
=> area of traingle = 1/2*4*6
=> area of traingle = 12 m^2
=> now , area of figure = 240 m^2 - 12 m^2
=> 228 m^2
hope it helps
