Step-by-step explanation:
my best estimate would be A. or C. just from the process of elimination
If no base is mentioned, asssume base 10
remember

translates to

so
since no base mentioned, assume base 10

translates to

then
1000=2x
divide both sides by 2,
500=x
Simplify.
3x^2−7x+9 - 2x^2+4x−8
1. 3x^2-2x^2 = x
2. -7x + 4x = -3x
3. 9 - 8 = 1
Combine.
x -3x +1
Thus, 2x^2+4x−8 is x -3x +1 less than 3x^2−7x+9
I believe the last answer would be correct.
Hello!
The Associative Property of Multiplication states the following:
a × (b × c) = (a × b) × c
The equation given in the image above follows the same form:
9 × (5 × 2) = (9 × 5) × 2
Therefore, the given equation must be representative of the Associative Property.
I hope this helps!
