Simplify. remove grouping sbols and combine like terms
harina [27]

Answer:

5a^2+12b^2-40b

Step-by-step explanation:

First distribute the -4 to the 2b and -3b. This leaves you with 5a^2-8b+12b(b+4)

Now you can distribute the 12b to b and +4. This leaves you with 5a^2-8b+12b^2+48b

Now you can combine your like terms leaving you with 5a^2+12b^2-40b.

The clownfish kay wanted to buy for $12 last week has been marked up 8%. What is the new price of the fish?
Crank
The markup is 8%, meaning it costs 8% more.
The starting price is 100%.
Therefore, the markup is 108% of $12.
If we multiply 12 by 108% (1.08), we will get our answer of $12.96

I need help with number 1-4 I don’t understand..
Karo-lina-s [1.5K]

Answer:

  1. 109°, obtuse
  2. 131°, obtuse
  3. 53°, acute
  4. 124°, obtuse

Step-by-step explanation:

You are exected to know the relationships of angles created where a transversal crosses parallel lines.

  • Corresponding angles are equal (congruent).
  • Adjacent angles are supplementary, as are any linear pair.
  • Opposite interior (or exterior) angles are equal (congruent).

The appearance of the diagram often gives you a clue.

You also expected to know the name (or category) of angles less than, equal to, or greater than 90°. Respectively, these are <em>acute</em>, <em>right</em>, and <em>obtuse</em> angles.

1. Adjacent angles are supplementary. The supplement of the given angle is 109°, so x will be obtuse.

2. Opposite exterior angles are equal, so y will be 131°. It is obtuse.

3. Opposite interior angles are equal, so w will be 53°. It is acute.

4. Corresponding angles are equal, so x will be 124°. It is obtuse.
