I got rid of the exponents (squared) by just multiplying them by themselves, BUT remember they were still Exponents (E below)
(11-6)(11-6) + 6 × 2 - (3+2)(3+2)
Follow your Order of Operation (OO):
One method is to remember the phrase "Please Excuse My Dear Aunt Sally", which forms the acronym [PEMDAS]. This stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".
So work your way from left to right, doing actions within parentheses first, next exponents... to lastly adding and or subtracting.
So we'll first do inside the parentheses:
(11-6)(11-6) + 6 × 2 - (3+2)(3+2) -->
(5)(5) + 6 × 2 - (5)(5) --> 25 + 6 × 2 - 25
Multiply (M) comes after E, so:
25 + (6×2) - 25 = 25 - 25 + (12) --> since 25-25 is 0, it's really just 0 × 12 = 12

the company sea esta has ten members on its board of directors. in how many different ways can it elect a president, vice-presid
Inessa [10]

There are 10 members on the board, so there are 10 ways to elect a president, 9 ways to elect a vice president, 8 ways to elect a secretary, and 7 ways to elect a treasurer.

This is because each position can be filled by any of the members, except for the position that the member is already filling. For example, the president can be elected from any of the 10 members, but the vice president must be elected from the remaining 9 members.

The company sea esta has ten members on its board of directors, so it has a lot of different options for how to elect a president, vice-president, secretary, and treasurer. One way to elect a president would be to have the board members vote on who they want to be president.

Another way to elect a president would be to have the members of the company vote on who they want to be president. There are many different ways to elect officers, and it really depends on the company and what they want to do.

The question is about unit circle in screenshot
Orlov [11]

The complete sentence for the <em>unit</em> circle is:

<em>When t = 0, AP = 0, so sin t will begin at a value of 0. As t increases from 0 to π/2, sin t increases. Eventually, when t = π/2, OP will be 0, so sin t = AP will be 1.</em>

<h3>How to complete a sentence with concepts from trigonometry</h3>

In this problem we have sentence to be completed by direct observation to the variables seen in a unit circle, a form used to teach trigonometric functions in a <em>graphic</em> manner. Now we proceed to present the complete sentence below:

<em>When t = 0, AP = 0, so sin t will begin at a value of 0. As t increases from 0 to π/2, sin t increases. Eventually, when t = π/2, OP will be 0, so sin t = AP will be 1.</em>
