You need the associative and commutative properties, but not the distributive property.
n*4n*9 =n*(4n*9) (associative)
= n*(9*4n) (commutative)
= n*(36n) (associative)
= 36n*n commutative
= 36*n^2

Choose the expression that correctly uses the distributive property to remove the parentheses from this expression. 3(n - 7) plus 4(n plus 2)?
It is: 3n-21+4n+8 = 7n-13 simplified
What does 4n to the second power means?
4n is multiplied by 4n.
What is 4 plus 4n -12?
4 + 4n - 12 = 4n - 8
What is 4n plus 3 equals 15?
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
What is 4n-1?
4n-1 = 3
What does 36(4n-5)45 equal?
Follow these steps 1. Using distributive property, first, distribute 36 into 4n and 45 so : 36x4n - 36x5 that becomes (144n-180)45 2. Distribute 45 to 144n and 180 so: 45x144n- 45x180 that becomes 6480n-8100 3. SImply by dividing by 1620 4n-5 so your final answer is 4n-5

Multiply 4 by n?
F(n) = 4n
4n divided by 7 plus 8 equals 20 solve for n?
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
What is 4n plus 2 times 5n minus one?
20n2+6n-2 (4n + 2)(5n -1) This problem can be solved by FOILing. First, multiply the first terms to get 20n2 Next, multiply the outside terms to get -4n. Multiplication of the inside terms results in 10n. Combining -4n and 10n (they are like terms) is 6n. Then, multiply the last terms, to get -2. Combining these answers into one equation gives the answer of 20n2+6n-2.
4n plus 2 equals 25 is an example of what property?
Equation
How do you show work by doing a soliving equations problem 40-4n equals 88?
40- 4n = 88 SUBTRACT 40 from BOTH SIDES -4n = 48 multiply BOTH sides by -1 4n = -48 divide BOTH sides by 4 n = -12
How do you solve a position to term rule using algebra?
4n+5
How do you write an equation or rule using a table?
n-12+4n++2_3n
What is the rule for 4n plus 2?
To find the nth number that is generated by the rule multiply n by 4 and then add 2.
What does 4n to the second power means?
4n is multiplied by 4n.
What it 4n - 14 equals 22?
4n -14 = 22 4n = 22+14 4n = 36 n = 9
