Answer:
3rd term: 24
10th term: 220
Step-by-step explanation:
<em>For the 3rd term</em>
2*3 + 2*(3^2) = 6 + 2*9 = 6 + 18 = 24
<em>For the 10th term</em>
2*10 + 2*(10^2) = 20 + 2*100 = 20 + 200 = 220
<span>6∙7-3^2∙9+4^3
= 42 - 9*9 + 64
= 42 - 81 + 64
= 25
answer
25</span>
Please see the pic, I'd solved in it.
Answer:
(x+1) (x^2+1)
Step-by-step explanation:
x^3+x^2+x+1
Factor by grouping
x^3+x^2 +x+1
Factor out x^2 from the first group and 1 from the second group
x^2( x+1) + 1( x+1)
Factor out (x+1)
(x+1) (x^2+1)
Answer:
x - 7/9 = f(x)^-1
Step-by-step explanation:
f(x) = 9x + 7
y - 7 = 9x
y - 7/9 = 9x/9
Interchange!
x - 7/9 = y
