I believe that x=4 would be the answer
Answer:
Step-by-step explanation:
Factor the sum of cubes
a³ + b³ = (a+b)(a² - ab +b²)
= 2a² - 2ab + 2b²
a³ + b³ + 6ab = 2a² + 4ab + 2b²
= 2(a² + 2ab +b²)
= 2(a+b)²
= 8
For perimeter you add up the two sides so 15 + 21 equals 36

Step-by-step explanation:
We are given that
On Monday
Mason ran distance =k Km
On Tuesday
Mason ran distance=
We have to find the expression which represents the distance ran by Mason on both days.
Total distance ran by Mason on both days
=


Hence, total distance ran by Mason on both days=4/3 k Km
