Answer:
4n-1
Step-by-step explanation:
n+3(n-1) ---> distribute the 3 to the (n-1)
n+3n-1 ---> combine like terms
4n-1
Answer: See explanation
Step-by-step explanation:
Yiur question isn't complete but I believe that you want to know the price of the soda.
Let the price of the soda be represented by x.
Jesean buys a pizza for 20$ and 10 drinks. This will be: 20 + 10x
He spends 32$ on the pizza and the sodas together. This can be formed into an equation as:
20 + 10x = 32
10x = 32 - 20
10x = 12
x = 12/10
x = 1.2
Therefore, the soda cost $1.20 each
<span>A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form? We want (n)(2n+6) - (n^2-1). (Please note: n^2 is correct, while n2 is not.)
Multiplying out the first term: 2n^2 + 6n
Subtracting n^2-1: - (n^2 -1)
----------------------
n^2 + 6n + 1 (answer) </span>
Answer: Problem 4, missing number is 626, while the missing number for all the other problems is 426.
Step-by-step explanation:
Problem 1. 526= _ + 100 (Ans = 526-100=426)
Problem 2. 526-_=100 (Ans = 526-100=426)
Problem 3. 526-100=_ (Ans = 526-100=426)
Problem 4. 526+100=_ (Ans = 526+100=626)
