Answer:
Yes
Step-by-step explanation:

If we say u = √n, then:

This is a geometric series. Since |1/e| < 1, the series converges.
It would 9x+20 because u have to distribute
Answer:
Step 1 and step 2
Step-by-step explanation:
she has to subtract 30 not add 30.
2(3x+6)=3(x-10)
6x + 12 = 3x-30
6x +12 - 12 = 3x - 30 - 12
6x = 3x - 42
6x - 3x = 3x - 42 - 3x
3x = -42
3x/3 = -42/3
x = -14
6 x 89 is 534
6 x (90 - 1) is 534. BUT you have to subtract 90 from 1 and that's 89. So then you multiply 6 by 89.
6 x 90 is 540 and 6 x 1 is 6. you take 540 subtract 6 and that's 534.
540 - 6 is 534.
