Multiplying polynomials
The document discusses three methods for multiplying polynomials: the distributive property, FOIL (First, Outer, Inner, Last), and the box method. It provides examples of multiplying polynomials using each method. The key steps of FOIL are to multiply the first, outer, inner, and last terms of each binomial being multiplied. The box method involves drawing a box and writing one polynomial above and beside the box before multiplying the terms. The document emphasizes that all three methods will provide the same answer when multiplying polynomials.
Adding and subtracting polynomials
Adding and subtracting polynomials involves combining like terms. Like terms are terms that have the same variables and the same exponents. To add polynomials, terms are grouped by their like terms and the coefficients are combined by adding them. To subtract polynomials, the process is the same as adding the opposite of the second polynomial. The opposite of each term is found by changing its sign. Then the like terms are combined in the same way as when adding.

Okay, let's think through this with the new information:
* The equation modeling the height is: h = -16t^2 + vt + c
* The initial height (c) is still 2 feet
* The initial velocity (v) is now 20 feet/second
* The target height (h) is still 20 feet
So the equation is:
20 = -16t^2 + 20t + 2
0 = -16t^2 + 20t + 18 (subtract 20 from both sides)
Evaluating the discriminant:
(20)^2 - 4(-16)(-18) = 400 - 288 = 112
Since the discriminant is positive

The nine building blocks of civilization
Technology advanced in Mesopotamia through irrigation systems, more efficient tools, and the pottery wheel. The Olmec civilization constructed colossal stone heads weighing tons that took thousands to carve, though their purpose remains unclear with multiple interpretations. Laws in early civilizations initially granted women rights but later restricted them, while slavery spread across Mesopotamia and religions influenced behavior through rituals and judgments of the afterlife.

Dewey decimal classification system
Melvil Dewey created the Dewey Decimal Classification (DDC) system when he was 21 years old to bring order to the organization of books in libraries. The DDC system divides all knowledge into 10 main categories, with each category represented by 3 numbers. These numbers can be found on the spine of each library book and help library patrons easily locate books on the shelves. The 10 main categories include generalities, philosophy, religion, social science, language, science and math, technology, arts, literature, and geography and history.

Organism Diversity in Ecosystems
Organisms diversify in an ecosystem by occupying different niches. An ecosystem can support many populations of different species because each population uses the ecosystem's resources in different ways. Populations are made up of the same species living in the same habitat. Multiple populations together make up the community of organisms in an ecosystem. Organisms avoid competition by occupying different niches defined by factors like habitat, food sources, behaviors, and activity times.

It then works through 4 example problems step-by-step, showing how to rename mixed numbers if needed so the fractions have a common denominator before adding or subtracting. The key steps are to rename any mixed numbers, find a common denominator for the fractions, then add or subtract the whole numbers and fractions.
2 24 Adding & Subtracting Fractions With Unlike Denominators
This document provides examples for adding and subtracting fractions with unlike denominators. It explains that to add fractions with different denominators, you must first find the least common denominator and convert the fractions so they have the same denominator.
