B. Associative and distributive properties.
C. Associative property.
Step-by-step explanation:
We proceed to present which reason are utilized by supporting procedure:
1) Given
2) A. Commutative property
3) B. Associative and distributive properties.
4) Addition.
5) C. Associative property.
6) Multiplication/Result.
Geometric mean would be 464
Answer:
x - 7 < - 12 A: -6 or less ... -7, -8, -9 etc
-9x (90) A: -10
3 + v > -9 A: -11 or more ... -10, 1, 0, 1238 etc
Step-by-step explanation:
1. if it has to be less than -12 the number must be farther left then -12
2. negative times negative = positive
3. use any number higher than -9
I believe it’s 600 because you have to multiply
Answer:
Step-by-step explanation:
Let's start by using distributive multiplication:
So:
Grouping like terms:
Now, is equal to:
In this sense:
In order to satisfied the equality:
Hence, from (1), let's solve for a:
And from (2), let's solve for b:
Let's verify the result evaluating the values of a and b into the original equation:
As you can see, the values satisfy the equation, therefore, we can conclude they are correct.
