Answer:
C
Step-by-step explanation:
A geometric series will only converge if - 1 < r < 1
sum to infinity = 
The nth term formula for a geometric series is
= a
where a is the first term and r the common ratio
The only summation with - 1 < r < 1 is C where r = - 0.2
Answer:
10x^2-11x-6
Step-by-step explanation:
To expand, we use the FOIL method. You do this by multiplying each number inside the parenthesis by the other numbers in the other set of the parenthesis. For example, on this problem, you would multiply 5x by 2x, and then 5x by -3.
Step by step, you would:
5x * 2x = 10x^2
5x * -3 = -15x
2 * 2x = 4x
2 * -3 = -6
In an equation, it would expand to 10x^2-15x+4x-6
To simplify, you add like terms (constants and those with the same variable). In this case, you would add together all the terms ending in x.
-15x+4x=-11x
Now, you have added like terms together, so your simplified answer is 10x^2-11x-6.
So find how much was eaten
1/6 and 2/3=eaten
add 1/6 and 2/3
convert bottom number to same
2/3=4/6
1/6+4/6=5/6
5/6 eaten
3-5/6=
2+1-5/6=
2+6/6-5/6=
2+1/6
2 and 1/6 waffles left

Step-by-step explanation:
Answer: D, -13<-10
Step-by-step explanation:
Which ever way the open part of the '<' is facing, means that it is greater than the other number.
-13 is smaller than -10 so the open part of the symbol would face towards -10 and the pointy part would fact towards the -13.
Hope this helps :)
