Answer:
Below.
Step-by-step explanation:
We can write an odd integer as 2x + 1 so consecutive odd digits would be 2x + 1 and 2x + 3, so the equation is:
2x + 1 + 2x + 3 = 156
4x + 4 = 156 can be used to solve for x and find the integers.
4x = 152
Dividing through by 4:
x = 152/4 = 38
So the 2 integers are 2(38) + 1 and 2(38) + 3
= 77 and 79.
8,000,000 would be the answer to 4000x2000. Hope this helps!
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
Hello :
<span>x+4y-2=5
multiply by 3 :
3x+12y -6 =5
(3x+12y-3)-3=5
conclusion :
</span>3x+12y-3 = 8
