Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
Three million, one hundred and fifty two thousand, three hundred and eight.

Answer:
48∛9 ft²
Step-by-step explanation:
Data
The area of the rectangular region is computed as follows:
area = length * width
area = 4 ∛24 * 6 ∛3
area = 4*6* ∛(24*3)
area = 24 * ∛(2³*3*3)
area = 24 * 2∛9
area = 48∛9 ft²
