The zero should be in the bottom right corner where it lists 1 and 1 it should be outside of the graph in the middle of 1 and 1
I wrote it out this time, so I didn't forget any work like last time. LOL
4x² - 16 is the algebraic expression that must be added to get the result as 9x²- 2x - 5.
<u>Step-by-step explanation:</u>
The question is asked for the algebraic expression must be added to the sum of 3x²+4x+8 and 2x2−6x+3 to give 9x²- 2x - 5 as the result.
Therefore,
The first step is to find of sum of 3x²+4x+8 and 2x²-6x+3.
To find the sum :
3x²+4x+8
<u>2x²-6x+3 </u>
<u>5x²-2x+11</u>
The sum is 5x²-2x+11.
Now, the second step is to subtract 5x²-2x+11 from the result 9x²- 2x - 5.
9x²- 2x - 5
- <u>(5x²-2x+11)</u>
<u> 4x² -16 </u>
Thus, 4x²-16 is the algebraic expression that must be added with 5x²-2x+11 to get a result of 9x²- 2x - 5.
Answer:
5(3x-2y)
Step-by-step explanation:
In this question we are given an expression 7 (x-2y) - 4 (2x+y).
Now, we have to simplify this expression after distribution.
So, 7(x-2y)+4 (2x+y)
=7x -14y +8x +4y {This is the distribution. Here we have used the distributive property that, a(b+c) =ab +ac}
=15x -10y {Separating the x and y terms}
=5(3x-2y) {Taking 5 as common from both the terms}
