Answer: 12a^3
Explanation: You would get the missing side to complete the perimeter by using the pythagorean theorem so 3^2+4^2=c^2 so you would get 9+16=c^2 which would become 25=c^2. That would get you 5 as the square root of 25 is 5 so in total, it would all be 3a^3+4a^3+5a^3 which would equal 12a^3.
(^ are for exponents) I might be wrong but hopefully it helps a bit. :)
Answer:
Distributive property says that:

Addition property of equality:
if x = y then x+z = y+z
Division property of equality:
if x = y then 
As per the statement:
Given the equation: 
Tyra solve this equation as shown below:
1.
[Distributive property]
2.
[Addition property of equality]
3.
{Division property of equality]
Therefore, the property Tyra used in line 1 was : Distributive Property.
Answer:
3
Step-by-step explanation:
because 3 is a prime number and 3+2=5 which is also a prime number
Answer:
56
Step-by-step explanation:
Round: 24 is 20 and 34 is 30
20 + 30 = 50
now unrounded, it's easier.
24 + 32 = 56
because 4 + 2 = 6, we know to add on only a few more.
