Answer:
Number of term = 48
Step-by-step explanation:
GIven:
Arithmetic progression
2,5,8..
Total sum of Arithmetic progression is 392
Find:
Number of term
Computation:
First term a = 2
Difference d = 5 - 2 = 3
Sn = [n/2][2a + (n-1)d]
392 = [n/2][2(2) + (n-1)3]
392 = [n/2][4 + 3n - 3]
784 = [n][1 + 3n]
784 = n + 3n²
3n² + n - 784
n = 48 , n = -49
Number of term = 48
Whats the question? I dont understand whats happenign here.
Answer:
9.18 feet
Step-by-step explanation:
dimensions of whole area = (20 + x)(34 + x)
= 680 + 54x + x^2
where x is the width of the flower bed.
we know that x^2 + 54x + 680 = 1200
x^2 + 54x - 520 = 0
x = 9.18 or x = -63.18
width of flower bed cannot be negative therefore it is width 9.18 feet
