ANSWER
C. 1, 5, 10, 10, 5, 1
EXPLANATION
We can quickly generate the Pascal's triangle as shown in the attachment.
In general this triangle, the extreme values are always 1.
The inner entries are obtained by adding the two entries directly above them.
From the Pascal's triangle, the coefficients in the expansion of (x+y)^5 are 1, 5, 10, 10, 5, 1
The correct choice is C

5-2 is 3. Subtract three from both sides. 2x=8. Divide by 2. X=4
Let's factorise it :
Using distributive property we get :
Therefore,
Answer:
x = 7
Step-by-step explanation:
123 = 17x + 4
123 - 4 = 17x
119 = 17x
119 / 17 = x
7 = x
The answer to this is A, C, and D.
