A store owner paid $20 for a book. She marked up the price of the book by 15% to determine its selling price. What is the selling price of the book?

A photograph is in the shape of a rectangle. It has a length of (x - 2) inches and a width of (x - 2) inches. What is the area of the photograph? Would this be [tex]x^{2}[/tex] + 4?
Answer:
yes
Step-by-step explanation:
two negatives make a positive and two x would make x squared
Answer:
You are actually off most people make that common mistake but the answer would actually be x^2 - 4x + 4, not x^2 + 4
Step-by-step explanation:
(x - 2) times (x - 2) = x^2 - 2x - 2x + 4 from here people tend to make a mistake by completely erasing out (-2x - 2x) thinking they cancel each other out, but here is what should have happened (-2x + -2x) = -4x so put it all together you would have x^2 - 4x + 4.
You can't do anything else because (+4) is a solid number of its own although there is an "x" in (x^2 and -4x) in "x^2" the x is with an exponent while in "-4x" the x is alone. It isn't the same as "x^2" so you wouldn't be able to get a proper answer even if you tried...it would most likely be an error

Answer:The mean is equal to the median.
Step-by-step explanation:
Median is the middle value of a given data set. In a symmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.
Step-by-step explanation:
One possible assignation can be:
from 0 to 2, the student buys lunch in the cafeteriafrom 3 to 9, the student brings lunch from home.How to assign the numbers?
We assume that in the spinner the probability of landing on each one of the given sections is the same.
So, to simulate a case where 30% of the students buy lunch in the cafeteria.
We need to assign 3 of the 10 sections to "buys lunch in the cafeteria" and the other 7 sections to "bring lunch from home"
That assignation can be made in any order you want, for example:
from 0 to 2, the student buys lunch in the cafeteriafrom 3 to 9, the student brings lunch from home.If you want to learn more about probability, you can read:

The system of equations has an infinite number of solutions as the two lines are coincident.
What are equations with infinite solutions?An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and slope, they are actually in the same line.
Given here the system of equations are: x+3y=0
12y=-4xor x+3y=0
thus both the equations are identical also their coefficients 1/1 = 3/3 so we can deduce the two lines are coincident with each other and therefore have infinite solutions.
Hence, The system of equations has an infinite number of solutions as the two lines are coincident.
