First we have to combine like terms. 4x² is one term. -8x is another term. -7 is another term. poly = "many" ⇒ polynomial = many terms
(4x² - 8x - 7) + (-5x + 16)
4x² - 8x - 7 - 5x + 16
Combine like terms.
Step 1: 4x² has no other terms with x² so it stays by itself.
Step 2: -8x and -5x are like terms because they both have x.
So -8x -5x = -13x (You put two negatives together)
Step 3: -7 and 16 don't have any x with them. -7 + 16 = 16 - 7 = 9
Now we put all the answers of the steps together.
Step 1: 4x²
Step 2: -13x
Step 3: 9
So the answer is 4x² - 13x +9
And it's a polynomial because there are three terms = "more than one term"

Hello there,
Friends house: 12 miles
Average: 2.5 mph
Write a proportion...
12/x = 2.5/1
Cross multiply and divide...
12 * 1 = 12
12/2.5 = 4.8 hours
Convert that into time...
4.8 hours or 5 h 20 m
Hope I Helped!!

Hello!
This is a problem about relating values of the Unit Circle.
First, we need to figure out the specific "points" of each angle measure of 30 and 60.
For the angle measure 30, the point will be
.
For the angle measure 60, the point will be
.
The tangent value of a point will be its
value over its
value.

The cotangent value of a point will be the reciprocal of the tangent value, which we found previously.

The sine value of a point will be the
value of the point.

So the values we have so far are 
Now we have to find the LCD to add these together, which in this case would be 6.

Which adds up to
, which is in simplest radical form.
Hope this helps!
