It is: 3n-21+4n+8 = 7n-13 simplified
4n is multiplied by 4n.
4 + 4n - 12 = 4n - 8
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
It is simply: 4n as an algebraic term
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
It is: 3n-21+4n+8 = 7n-13 simplified
F(n) = 4n
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
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.
Equation
40- 4n = 88 SUBTRACT 40 from BOTH SIDES -4n = 48 multiply BOTH sides by -1 4n = -48 divide BOTH sides by 4 n = -12

To find the nth number that is generated by the rule multiply n by 4 and then add 2.
4n is multiplied by 4n.
4n -14 = 22 4n = 22+14 4n = 36 n = 9
