Answer:
Company A:
c = 40 + 2s
Company B:
c = 20 + 4s
Equal costs => 40 + 2s = 20 +4s => 4s - 2s = 40 - 20 => 2s = 20 => s = 20/2
=> s = 10
And c = 20 + 4s = 20 + 4(10) = 20 + 40 = 60
Step-by-step explanation:
Check the picture below.
the volume of the prism will simply be the product of the triangular area and its length, it has a length of 8, thus

Answer:
2(x+y) - 23 or
2x + 2y - 23
Step-by-step explanation:
twice the sum of x and y means
2(x+y)
decreased means minus or -
decreased by 23 means
- 23
twice the sum of x and y decreased by 23
2(x+y) - 23
2(x+y) = 2x + 2y
2x + 2y - 23
