Answer:
15x + 15
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of variables. Set the equation so that the terms are grouped:
6x + 9x + 6 + 9
Combine like terms:
(6x + 9x) = 15x
(6 + 9) = 15
15x + 15 is your answer.

Answer:
- wrong: -2x² -x² ⇒ -2x²
- correct: x³ -3x² +6
Step-by-step explanation:
The point of these "what was done wrong" exercises is to see if you know what the correct steps look like.
On line 2, Danielle correctly distributed the minus sign to eliminate the second set of parentheses. (There is often a problem with minus signs and parentheses, so it is nice to see it done correctly.)
On line 3, the two x² terms are incorrectly combined. It looks as though Danielle simply dropped the -x² term because it disappeared without changing the coefficient of x² from -2x². The correct sum of those terms is ...
-2x² -x² = -3x²
so the correct work on line 3 is ...
x³ -3x² +6
Hi there...
the point slope formula is
y-y1=m(x-x1)
where y and x represent any points
y1 and x1 represents known points
and m represents the slope
Answer:
i believe the correct answer would be 64 cm
