<span>Combine like terms : (v2 - 5) x (3v + 7)</span>
Answer:
The answer to your question is the letter B
Step-by-step explanation:
Data
| 5 0 | | 2 - 1 |
| 3 -5 | | 2 - 2|
Process
1.- This is the product of two matrices 2 x 2 so the result will be a 2 x 2 matrix.
- Multiply the first row of the first matrix by the first column of the second matrix.
-Multiply the first row of the first matrix by the second column of the second matrix.
- Multiply the second row of the first matrix by the first column of the second matrix.
-Multiply the second row of the first matrix by the second column of the second matrix.
| 5 0 | | 2 - 1 | | (5 x 2) + (0 x 2) (5 x -1) + (0 x -2) |
| 3 -5 | | 2 - 2| = | (3 x 2) + (-5 x 2) (3 x -1) + (-5 x -2)|
= | 10 + 0 -5 + 0 |
| 6 - 10 -3 + 10|
= | 10 - 5 |
| -4 7|
D because if it’s liner then it’s probably positive... I’m not sure
Answer:
x=3
Step-by-step explanation:
1) get rid of the parenthesis by distributing the 2. You will get 8x-6-8=4+2x
2) Now combine like term on each side of the equal sign. You will get 8x-14=4+2x
3) Move the 14 to the right side of the equation making it +14 and move your 2x to the left side of the equation making it -2x. You will get 8x-2x=4=+14
4) calculate each side. You will get 6x=18
5) Divide both sides. You will get x=3
