If they are the sides of rectangle, then it's perimeter would be:
2(l+b) = 2(24.5+31.7) = 2(56.2) = 112.4

Answer:
(a - b)(a² + ab + b²)
Step-by-step explanation:
The difference of cubes is expressed as:
a³-b³
Using trial and error:
a³-b³
Check (a - b)(a² + ab + b²)
Expand
(a - b)(a² + ab + b²)
= a(a²)+a(ab)+a(b²)-a²b-ab²-b³
= a³+a²b+a(b²)-a²b-ab²-b³
Collect the like terms
= a³+a²b-a²b+ab²-ab²-b³
= a³-b³
Hence the required option is
The solutions for the following expressions are:
1. 0.5*2 = 1
2. -0.2+-0.05= -0.25
3. absolute value of (-3+2.75) = 0.25
4. -(-0.25) = 0.25

Answer:
By adding all the numbers and then divding them by 6 (since thats how many numbers there are) you will get 9.833...
