In a regular polygon, all of the sides have the same length.
Pentagons have five sides. If one of the sides in a regular pentagon is 4 feet, then the rest will also be four feet. 5 sides that are all 4 feet long totals up to a 20-foot perimeter.
Answer:
A
Step-by-step explanation:
Use foil to expand it.
y = 4 (x^2 + 7x - 9x - 63) Combine the like terms on the right.
y = 4(x^2 - 2x - 63) Use the distributive property to remove the brackets.
y = 4x^2 - 8x - 4*63 Combine the two multiplied factors on the right.
y = 4x^2 - 8x - 252 4* 63 = 252
The answer is A
Answer:
y - 4 = 0
Step-by-step explanation:
They give you the y coordinate, 4, and the x coordinate as 0.
Put 4 in as y.
4 - 4 = 0. That means x = 0 and that is right.
To make sure it has a slope of zero, subtract 4 on both sides.
You get : y = 4. This means that the line will be straight and it will have a slope of zero.
This isn't a question. What is the question?
Given:
To find:
The quadrant in which 
lie.
Solution:
Quadrant concept:
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II, only 
and 
are positive.
In Quadrant III, only 
and 
are positive.
In Quadrant IV, only 
and 
are positive.
We have,
Here, is negative and is also negative. It is possible, if 
lies in the Quadrant IV.
Therefore, the correct option is D.
