The expression to be simplified is: (9x^2 - 25) / (3x + 5)
We first factor the numerator: 9x^2 - 25 is a difference of two squares, (3x)^2 - (5)^2, so this can be factored into (3x + 5)(3x - 5).
Then the expression becomes (3x + 5)(3x - 5) / (3x+5), and the 3x + 5 term cancels out, leaving just 3x - 5 as the final answer.
Answer: At least 4/14 = 28.5%
Step-by-step explanation:
Select the location of a math book at the far end. The probability that the book next to it is a math book:
4 remaining math books, out of the 14 remaining books
In the middle, there are two potential spots adjacent to each book, so it could be higher - that’s why I say “at least” 4/14

Answer: and Step-by-step explanation: The matrix L is of form 2x3, in which therentwo rows, representing Costa Rica and Honduras, respectively, and 3 columns, representing pair of shorts, tee shirt and cap, respectively:
L =
The matrix M is also a matrix of form 2x3:
M =
Matrix C is the total cost of both countries, then:
C = L + M
C = +
To add 2 matrices, you have to add the first term of the first matrix to the first term of the second matrix and so on:
C =
C =
The total cost for the products in each country is
C =
