Answer:
A.
Step-by-step explanation:
Rectangle: Length * Width
—> 12 * 2 = 24
Triangle: Base * Height * 1/2
—> 12 * 2 * 1/2 = 12
Matches answer A.
Answer:
A. 13m
Step-by-step explanation:
To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.
13 x 13 = 169

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>
In this question we have <em>trigonometric</em> expression whose equivalence to another expression has to be proved by using <em>algebra</em> properties and <em>trigonometric</em> formulas, including the <em>fundamental trigonometric</em> formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:
Given.
Subtraction between fractions with different denominator / (- 1) · a = - a.
Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)
Definition of tangent / Result
By using <em>algebra</em> properties and <em>trigonometric</em> formulas we conclude that the <em>trigonometric</em> expression is equal to the <em>trigonometric</em> expression . Hence, the former expression is equivalent to the latter one.

I like that you left How you did it on there. When I was in school I did it the same way. I would assume you’re using is over of equals percent over 100. The problem however is that the above number is always the total which means it should be on the bottom.
X/72= 45/100. Similar to what you have written. Solve the proportion. 100x=72x45
100x= 3240
X = 32.4
Answer:
Option 2)
Step-by-step explanation:
In a function, any number can be an x-coordinate only once.
Option 1) The 2 appears twice as x.
Option 2) All x-coordinates are different.
Option 3) The 2 appears twice as an x-coordinate.
Option 4) The 3 appears twice as an x-coordinate.
Answer: Option 2)
