<span>Think about the cones with only 1 scoop of ice cream. Isn't it clear that there are 28 of those?
Now think about the two scoop cones. You have 28 choices for the first scoop and 28 choices for the second scoop.
So the number of possibilities is 28(28).
Now think of the 3 scoop cones.
You have 28 choices for the first scoop, 28 choices for the second scoop, and 28 choices for the third scoop or 28(28)(28) possibilities.
Add them all together and you have the total.
So it will be like this:
</span><span>28^3+28^2+28

I hope my answer helped you.
N is the term that you are looking for. it asked for the 3rd term so you replace n with 3. now its : 3 x 3^2 + 4 . you use the order of PEMDAS:
P arenthesis
E xponents
M ultipication
D ivision
A ddition
S ubtraction
you start with parenthesis but there are none so now exponents. 3^2 is 3 x 3. that would be: 3 x 3 = 9.
now multiplication. 3 x 9 + 4. 3 x 9 = 27
now division. there is none. so now addition and there is. 27 + 4 = 31.
then subtraction but there is none. so now you are done.
the 3rd term is therefore 31.
i hope that i helped.
Answer:
−1.2c+6.3
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
<u>Given</u>
2x^2-5+1=3
<u>Combine like terms</u>
-5 + 1 = -4
2x^2 - 4 = 4
<u>Add 4 to both sides</u>
2x^2 = 8
<u>Divide both sides by 2</u>
8/2 = 4
<u>Simplify</u>
x^2 = 4
<u>Square both sides</u>
<u>Simplify</u>
x = 2
<u>Answer</u>
x = 2
