Answer:
4×⁴+3׳+7ײ-3x+4
Step-by-step explanation:
First remove the parentheses and pair up like terms
4×⁴+3׳+2ײ+5ײ-x-2x+1+3
Then combine the like terms
4×⁴+3׳+7ײ-3x+4
Which is the answer.
5 * 198 = 990
198
* 5
-------
990
On your calculator your write 8 on the y axis and 4 on the x axis
The GCF of the three terms (9a, -18b and 21c) is 3
Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c
So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)
Answer: 3(3a - 6b + 7c)
If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
