The answer is B.
Do you need the explanation?
<span> (3x^3 - 7x^2 + 12) - (3x^3 + 6x^2 + 10x)
</span>First, remove parentheses
3x^3 - 7x^2 + 12 - 3x^3 -6x^2 -10x
eliminate the opposites
then collect the like terms
13x^2 +12 - 10x
and finally, use the commutative property to reorder the terms, and you'll get
-13x^2-10x+12
Answer:
Hello! answer: e = 108 d = 32 f = 40 because
108 + 108 + 32 + 32 + 40 + 40 = 360 Hope this helps!
For the first one it would be C and the second one would be B
Answer:12
Step-by-step explanation:
Answer:
Last option: Square both sides of the equation in step 1 to eliminate the square root.
Step-by-step explanation:
The error is in the process of subtracting 3 from both sides, since +3 is inside the root.
In order to be able to operate with the terms that are inside the root, we need to eliminate the root, and for that we need to square both sides of the equal sign.
