Answer:
8x²- x -8
Step-by-step explanation:
The question is not well written. I guess what you mean is:
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9, that is
6x^2+3x-9 - (-2x^2+4x-1). This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes
8x²-x -8
The answer is 8x²-x -8.
Option A:
6 – 4(3) < 5 – 10
Solution:
Given expression is 6 – 4(3) ____ 5 – 10.
Let us first simplify the expression.
Take left side expression.
⇒ 6 – 4(3)
⇒ 6 – 12
⇒ –6
Take right side expression.
⇒ 5 – 10
⇒ –5
To find which symbol makes the expression true.
In negative the highest number is the lowest in value.
–6 < –5
⇒ 6 – 4(3) < 5 – 10
Option A is the correct answer.
Hence 6 – 4(3) < 5 – 10.
