Simplify 4x + 8x using the properties of operations.
A. 12x
B. 4 + 8x
C. 12x²
D. 4x + 8
The simplified form of 4x + 8x is B. 4 + 8x.
Choose A., B., C., or D.
I apologize for the previous response. The correct simplified form of 4x + 8x is D. 4x + 8.
Simplify 9g - 7h- 6g- + 2h.
A. 2gh - 4gh
B. 3g - 5h
C. -2gh
D. 3g + 5h
To simplify 9g - 7h - 6g + 2h, we can combine like terms:
9g - 6g - 7h + 2h
(9g - 6g) + (-7h + 2h)
3g - 5h
Therefore, the simplified form is B. 3g - 5h.
To simplify the expression 4x + 8x, we can combine the like terms by adding the coefficients of x.
Like terms are terms that have the same variable, in this case, x.
So, 4x + 8x can be simplified as (4 + 8)x.
Adding 4 and 8 gives us 12, so the expression simplifies to 12x.
Therefore, the correct answer is A. 12x.
