When multiplying two terms which have the same base (in this case, -9), the base remains the same and you add the exponents together.
Here is a generic example: (xn)(xm) = xn+m
For your specific question, the base (x) is -9, the first exponent (n) is 10, and the second exponent...

A table of values can be created by choosing a value for X, plugging in that value in the equation, and then using the result as the Y value as seen below (I'm sorry I don't have a better way to represent the table):
X -4 -3 -2 -1 0 1 2 3 4 ...

This problem involves more reading comprehension than math! You need to translate the words of the problem into expressions using only numbers and variables:
Assuming L is length and W is width.
"The perimeter of rectangle is 50 meters" 2L + 2W = 50
"The length...

A "trick" to factoring trinomials is to use the product-sum method which, when the trinomial is written as x^2+Bx+C, begins with finding two numbers which add to equal B and multiply to equal C.
In the problem given, x^2 + 4x + 3, the B value is 4 and the C value...

If we want to know the fewest number of students in the computer lab club, we must attempt to minimize the other portions of the word problem as well. Since you can not have a fraction of a computer, we can assume the fewest number of computer stations available in the technology lab is 8 since...
