Answer:
a(n) = a(1) + 6(n -1)
Step-by-step explanation:
The common difference here is 6. 1 + 6 = 7; 13 + 6 = 19; and so on.
Thus, the function in question is a(n) = a(1) + 6(n -1).
13 m is the volume of the prism
Answer:
3 < x+4
Step-by-step explanation:
The less than symbol is <
3 is less than the sum ( add) of x and 4
3 < x+4
Solving
Subtract 4 from each side
3-4 < x+4-4
-1 <x
Answer:
Okay so I am assuming you mean the third part?
Step-by-step explanation:
Pretty simple. So you see that the varible x^2 does not have a number in front of it, so there is no extra dividing.
A formula for a perfect square is (x^2)+2xy+y^2
Take 10 and divide it by 2.
10/2=5
You have Y. Finding the third part is squaring Y.
5^2=25
Therefore, the third part of the perfect square is 25. If you want to find Y, look at the stuff above.
