Answer:
This is an equation.
Step-by-step explanation:
An expression would mean that there is no equal sign, but since there is, that makes it an equation.
917 - 67 = 850 (subtract the difference)
850 / 2 = 425 (divide the cost of the washer/dryer)
425 + 67 = 492 (add the difference)
The dryer costs $492.
Answer: 
, where n is a natural number.
Step-by-step explanation:
A series can be represented in a summation or sigma notation.
Greek capital letter, ∑ (sigma), is used to represent the sum.
For example: 
, where n is a natural number.
The given series : 1,4,9,16 which can be written as 
.
So , we can write it as
, where n is a natural number.
Sometimes complex information all at once can be hard to gather... Simplifying ideas and concepts can help with the amount of cramming you're giving to your audience.

The little square box in the corner between the vertical line and the horizontal one is a symbol indicating that angle is a right angle. It has a measure of 90°. The angles designated 1 and 2 together add up to that 90°. When angles sum to the value 90°, they are called "complementary" angles.
Since angles 1 and 2 also share a side and a vertex, they are also "adjacent" angles.
The appropriate choices are ...
- complementary angles
- adjacent angles
___
<h3>2.</h3>
The same lines define the sides of angles 1 and 2, and they share a vertex. However, they are not adjacent. They are ...
___
<h3>3.</h3>
The angles marked 157° and x° together add up to make a line, so they are supplementary (their total is 180°). They also share a vertex and a side, so they are adjacent. The appropriate choices are ...
- supplementary angles
- adjacent angles
___
<h3>4.</h3>
When two angles total 180°, they are <em>supplementary</em>, whether they have any common parts or not. Since 98° + 82° = 180°, ...
- The angles are supplementary
