Answer

5) (5p+9)(p-2) 6) 3(k+7)(3k+1) 7) (b+7)(2b+3) 8) (x+2)(2x+1)

Step-by-step explanation:

its kinda hard to explain cause all i have to say is factor out the numbers that are either in the second parenthesis to get the numbers in the first or vice versa. if i want to get into more detail, the fist equation becomes 5p^2+9p-10p-18 and then you factor.

galina1969 [7]

Answer:

1. $a_n=a_1+(n-1)d$

2. $a_n$ $=a_n_-_1+a_n_-_1(0.07)$

Step-by-step explanation:

For case 2 the population grows by 170 per year. Therefore for year t=0 its 2000 and t=1 then the population is 2170 and t=2 population is 2340. We can express the sequence as:

$a_n=a_1+(n-1)d$

We know the difference is d=170 and n=1,2,3....:

Case two can be define by:

$a_n$

$=a_n_-_1+a_n_-_1(0.07)$
