I think it's true because both opposite sides are always the same.
Let’s use m for months
So,
1st service
10m + 20
1. 10 + 20 =30
2. 10x2=20+20=40
3.10x3=30+20=50
4.10x4=40+20=60
5.10x5=50+20=70
2nd service
11m + 15
1. 11+15=26
2. 11x2=22+15=37
3 11x3=33+15=48
4.11x4=44+15=59
5.11x5=55+15=70
So, the 5th month the services cost the same
Hope this helps! ;)
x+x+x+2 = 3x+2
So,
A is correct
B is wrong
C is wrong
D is correct [2x+2+x = 3x+2]
E is wrong

Answer:
1872 cm cubed
Step-by-step explanation:
Volume=Length*Height*Width
We know that the height of the prism is 13 cm.
We also know that the lateral area of the prism is 634 cm squared.
624/4=156
The area of each lateral face is 156 centimeters squared.
The prism's base is a quadrilateral that is regular. This means that the base has equal sides (equilateral) and equal angles (equiangular ).
13x=156
x=12
The base has a side length of 12 cm.
12*13*12=1872
