The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is

Where a is the first term, n is the nth term, d is the common difference
On substituting there values,we will get

= 15(84000+52200) = 15*136200 =2043000
And for company A, it is

Difference between them =2043000-2002500= 40500
So the correct option is the second option .

Volume of the cube = a³ = (14cm)³= 2744 cm³
To find surface are, we need to find at first area of the face
A(face)=14² cm².
Cube has 6 congruent squares, so
Surface area of the cube = 6*14² cm²= 1176 cm²

Ans = 2x² - 9x + 10
BRAINLIEST PLS!!!
Seth traveled 1mi/57.1s
you need to convert mi/s to mi/h
we need to found how many seconds are in an hour (3,600)
so 3,600/57.1=63.047
63.047mi/h
63mi/h (rounding)
