1. when you see 4(x² - 1), then you have to multiply 4 with everything in the bracket. keep in mind that you always have to be cautious of the sign whether it is a positive or a negative.

positive ×/÷ positive = positive
negative ×/÷ negative = positive
positive ×/÷ negative = negative
negative ×/÷ positive = negative

^ you have to remember this.

2. only like terms (same alphabet) can plus or minus each other.

3. simplify by taking out the common factor and placing it outside the bracket.

Jennifer wants to make a large container of lemonade. When she makes a full glass of lemonade she uses 5 drops of flavor and 12
Julli [10]

The information we have is:

5 drops of flavor are needed for 12 ounces of water.

To solve the problem, first we need to find the amount of drops needed per ounce of water, and then multiply that by the number of ounces that we need which is 1280.

The number of drops per ounce:

To find this, divide 5 drops by 12 ounces:

\frac{5}{12}

5/12 drops are needed per ounce.

The number of drops in 1280 ounces:

Now we multiply 5/12 by 1280:

\frac{5}{12}\times1280

And the result is:

\frac{5}{12}\times1280=0.41666\times1280=533.333

The number of drops needed is: 533.333

Answer: 533.333 Drops

Give one example of when you would draw a diagram to solve an angle measurement problem
adell [148]

An example of an angle measurement problem is when trying to calculate for the height of a particular object given the distance of the observer from the object and the angle of elevation or depression.  For example, you want to find out the height of a building. All you need to know is the distance of your point of origin to the building and the angle of elevation.
