Answer:
A. The shopper receives a discount now and pays sales tax on the
discounted price of the item. I think, makes most sense
Answer: D. 8x² + x + 3
Sum means the answer to an addition problem. To find the sum of polynomials, we will add like terms.
<h2>What are like terms?</h2>
Like terms can be combined using addition or subtraction and have the same variables. Constants are also like terms with each other because they have no variables.
<h2>Solve</h2>
(4x² + 1) + (4x² + x + 2) Starting equation from the question
= 4x² + 1 + 4x² + x + 2 Remove brackets
= 4x² + 4x² + x + 1 + 2 Rearrange to group like terms together
= 8x² + x + 1 + 2 Add like terms with the same 'x²' variables
= 8x² + x + 3 Add like terms that are constants

Answer:$80.24
Step-by-step explanation:68*0.18(18%)
12.24
68+12.24=$80.24
5.77
By 0.07
Because if you subtract 0.07 from 5.77, you get 5.7, so it must be smaller.
