Oh, dude, that's like adding 2 apples to 3 apples, you know? So, if you have 2n and then add 3n, you end up with 5n. It's like math, but with letters instead of numbers.
The expression 3n times 3n can be simplified by multiplying the coefficients (3 * 3) and adding the exponents (n + n). This results in 9n^2, where n is raised to the power of 2. This simplification follows the rules of exponentiation, specifically the rule that states when multiplying two terms with the same base, you add the exponents.
Yes when multiplying. No when adding. 3n^3 + 3n^3 = 6n^3 3n^3 x 3n^3 = 9n^6
Negative plus a negative is a negative. Ex. -1+-1=-2 Negative times a negative is a positive. -2*-2=4 But a negative [minus] plus a positive [plus] can be minus, zero or plus: For example, -3 + 2 = -1 -3 + 3 = 0 -3 + 4 = +1
3n+2 + (3n+3 - 3n+1) = 3n+1+1 + (3n+1+2 - 3n+1) = 3*3n+1 + (9*3n+1 - 3n+1)= (3+9-1)*3n+1 = 11*3n+1.
3n+1=7 3*2+1=7
3 + 3n = 9 + 2n + 4n n = -2
Simplify -6n+2+3n-3 So first let's combine the n terms. -6n and 3n is -3n since -6 and 3 is -3. Or, think of being in debt 6 dollars as -6n and someone gives you 3 dollars just because they are nice like those people who answer WikiAnswers.com. Now you are only in debt 3 dollars which we denote as -3 and n could be dollars or cents. Bottom line, when you combine the n's it is -3n. Next combine the numbers or constant terms, 2-3 is the same as 2+ (-3) which is -1. So the answer is -3n-1 which can also be written as -(3n+1)
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
for the sequence, 3n +1, where n = 1,2,3,4......n =1: 3*1 + 1 = 3 + 1 = 4n =2: 3*2 + 1 = 6 + 1 = 7n =3: 3*3 + 1 = 9 + 1 = 10n =4: 3*4 + 1 = 12 + 1 = 13
2 + 3n = 4subtract 2 from each side2 - 2 + 3n = 4 - 23n = 2divide both sides integers by 3(3/3)n = 2/3n = 2/3=========check in original equation2 + 3(2/3) = 42 + 6/3 = 42 + 2 = 44 = 4=======checks
The Series has the formula 3n + 1/2(n - 1)(n - 2) = 3n + 1/2(n2 - 3n + 2) which simplifies to, 1/2(n2 +3n + 2)
There is not sufficient information to answer this question.There must either be a value for n if you are solving what "3n+1" equalsOR"3n+1" must equal something if you are solving for n.
It depends! What is the value of N? Example If n= 3, the answer would be 11 (3n= 3x3=9 the plus the 2) Example 2 If n=7, ten the answer would be 23 (3n= 3x7=21 plus the 2wouldbe 23) Hope this helps
