I THINK it's possibly distributive??
The correct answer here would be D. -1(3x+1)(x+5). You can find this answer by redistributing the problem.
-1(3x+1)(x+5)
-1(3x²+15x+1x+5)
-1(3x²+16x+5)
-3x²-16x-5
Using the math above, we can see that when we redistribute we get the original equation. That makes Choice D correct.
Answer: A. 1/4n - 2 = 10
Step-by-step explanation:
1/4n = One-forth of a number
-2 = Two less than
= 10 = is 10
The answer is 21 because times the bottom and top by 3 and 2 x 3 is 6 as there are 6 red pencils and 7 x 3 is 21.
