You start off by multiplying the second bracket by -1 to get rid of the bracket.
So,
(2x3 + x2 - 4x) - 9x3 + 3x2 =
2x3 +x2 - 4x - 9x3 + 3x2 =
(2x3 - 9x3) + (x2 + 3x2) - 4x =
-7x3 + 4x2 - 4x
Answer:
That's great for Brad, wait are you talking about the Brad from clash royale? if so im impressed
Step-by-step explanation:
By using two arbitrary points on the line, we can find the slope using the slope formula:

We'll use the points (0, 4) and (5, 1) for this.
1 - 4 / 5 - 0
-3 / 5
The slope of the line is -3/5.
2x4=8 2x2=4 4+8=12, so it is A
Answer is A, y us smaller/equal to 2 and y is smaller/equal to X
