Okay so you split 9ab + 12ax - 6b - 8x
<span> into two 2-term polynomials </span>
+ 12ax + 9ab and - 6b - 8x
doesn't look that good to me so lest try other one :
9ab + 12ax and - 6b - 8x
looks good for now
<span> </span> Pull out from each binomial separately
9ab + 12ax = 3a • (3b + 4x)
- 6b - 8x = - 2 • (3b + 4x)
<span> </span> Add up to arrive at the desired factorization so now you have
<span> (3a - 2) • (3b + 4x)

Hope that Helped!</span>
Answer:
82
Step-by-step explanation:
The sum of scores for the 9 tests must be 90 * 9 = 810. The sum of scores for the 8 tests is 8 * 91 = 728 so the lowest score is 810 - 728 = 82.
A1 = 9 × 1 - 6 = 3
A2 = 18 - 6 = 12
A3 = 27 - 6 = 21
A4 = 36 - 6 = 30.
Step-by-step explanation:
Σ ( 9n - 6 ) , n = 1
An = general term.
let Σ (An) = Σ (9n-6)
An = 9n-6
to determine the terms, plug in the value of n into the general term(An)
If you're asked for the 1st term then n = 1
if you're asked for the 2nd term then n = 2. and so forth.
To find the 1st 4 terms, just plug in 1 up to 4 into n bit by bit.
An = 9n - 6
A1 = 9 × 1 - 6 = 3
A2 = 18 - 6 = 12
A3 = 27 - 6 = 21
A4 = 36 - 6 = 30. done.
write the terms from 1 to 4 like this :
{ A1, A2, A3, A4 } = { 3, 12, 21, 30 }.
