Note that both sides were multiplied by 5.
So that would be "Multiplication Property of Equality."
Basically, this property states that if a=b, then ac = bc.
Answer:
infinite solutions
Step-by-step explanation:
3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)
Combine like terms
3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)
15(12x2+x+1) = 15(12x2+x+1)
Divide by 15
(12x2+x+1) = (12x2+x+1)
Since they are the same
x can be any real value
Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out
Answer:
the second person because they make 12 an hour and the first person only makes 9 an hour
Step-by-step explanation:
The answer is
C. (x+3)(5x2-2)
