We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896

Answer:
Ok so here's your answer, so 3 = 1.73,
Step-by-step explanation:
70/3
6x > 220 - 80
220 - 80 = 140
6x > 140
Divide 6 on all terms & simplify.
6x/6 > 140/6
Divide x by 1 and cancel common factor 140/6
x > 140/6
Factor 2 out of 140
x > 2(70) / 6
Cancel common factors
Factor 2 out of 6
x > 2 • 70 / 2 • 3
Cross out both of the 2’s and rewrite expression
x > 70/3 or (70/3 , ♾ )
