3n4+21n3+27n2

Enter your answer in the box.

To factor out the expression we look for number which is divisible by every term in our case it is 3n^2:

3n^4+21n^3+27n^2

we first begin by factoring out 3n^2, this will give us;

3n^2(n^2+7n+9)

hence, since we cannot factorize the quadratic expression the answer remains to be:

3n^2(n^2+7n+9)

Step-by-step explanation:

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
