Answer:
Interpolation refers to using the data in order to predict data within the dataset. Extrapolation is the use of the data set to predict beyond the data set.
Step-by-step explanation:
Extrapolation and interpolation are both used to estimate hypothetical values for a variable based on other observations. There are a variety of interpolation and extrapolation methods based on the overall trend that is observed in the data.

Step-by-step explanation:
Solution
I'm assuming you want this simplified. If not leave a note.
a(x + 1) - b(x + 1) - x - 1 remove the brackets
ax + a - bx - b - x - 1 gather like terms
ax - bx - x + a - b - 1
x(a - b - 1) + (a - b - 1) Use the distributive property to simplify
Answer
(x + 1)(a - b - 1)
The common factor is (a - b - 1). That can be pulled out on either side of the isolated + sign
The answer:
<span>according to the question the length is its width, that means
w=l
</span><span>She wants to enlarge the picture to have an area of 192 in2,
that means Area = </span>wxl = 192 in²
so, since w=l, we can write that Area = wxl =w²=l²= 192 in², this implies:
w=sqrt (192) = 13.85 in
finally the width w = 13.85, and the length l= 13.85 because w=l
Answer: It took her 11 days to read Part 1 of the book.
Step-by-step explanation:
380 - 20d = 160
Subtract 380 from each side
-20d = -220
Divide each side by -20
d = 11
