Answer:
(c) 2440
Step-by-step explanation:
The sum of the squares of numbers 1 .. n is ...
s(n) = n(n +1)(2n +1)/6
You want the sum of squares from 5 to 19. We can compute that from ...
s(19) -s(4) = (19(20)(39) -4(5)(9))/6 = (14820 -180)/6 = 2440
Let the number of days be x.
138 + 27x = 47 + 40x
40x - 27x = 138 - 47
13x = 91
x = 7
Ans: 7 days
Detailed working:
138 + 27x = 47 + 40x
138 + 27x - 27x = 47 + 40x - 27x
138 = 47 + 13x
138 - 47 = 47 + 13x - 47
91 = 13x
13x = 91
x = 91 ÷ 13
x = 7
Line AC has 7 spaces and line BE has 8
to know this you count from letter A to C which is 7. and then B to E which is 8
