Answer:
4
Step-by-step explanation:
47 - 43 = 4
For the answer to the question above,
2r^2 + 3s^3 - r^2 + 4t^2 - r^2
r = -2
s = -3
t = 5
First, we should substitute everything into the expression
(2)((-2)^2) + (3)((-3)^3) - (-2^2) + (4)(5^2) - (-2^2)
Now we should simplify the exponents
(2)(4) + (3)(-27) - (4) + (4)(25) - (4)
Now we simplify the brackets
8 + (-81) - 4 + 100 - 4
so 8 minus 81 minus 4 plus 100 minus 4 is equal to +19
I hope this helps.
Answer:
-30
Step-by-step explanation:
Since the first term is -3 and the common difference is 3, the equation for the nth term is
(Test it out!).
Therefore, the 10 term will be
which is
which simplifies to
which results in
.
Hope this helps :)
Answer:
1x
We do n-1 so the first term is 1x
and the pwoer of zero makes the number 1 so the pattern is still correct because 1x1=1
Double check the equation is true
Second term is 1x![5^{2-1}](https://tex.z-dn.net/?f=5%5E%7B2-1%7D)
1x5=5
If you don't want the equation you just multiply 5 each time
