x = 36
Answer:
A: 500 square feet
Step-by-step explanation:
A: First you have to draw a grid.
You plot the points A,B, and C.
The fourth point would be -5,25 because it matches with the points.
You make a rectangle out of those points
Points AB is 2 feet. Since the interval I used was 5 I would multiply 2 by 5 to get 10.
Then I would find Points BC which is 10 feet. Again multiply it by 5 to get 50.
50 x 10 is 500.
B: Jenna has to reflect over the y-axis. This is because the y-axis is between Quadrants II and I. When reflecting over the y-axis the y-coordinate stays the same but the x-coordinate switches to it's opposite. Basically the x-coordinate is negative in Quadrant II, but in when reflecting over the y-axis the x-coordinate would change to a positive in Quadrant I. So if the point in Quadrant II looks like this: (-X,Y) then when reflecting over the y-axis to Quadrant I would look like this: (X,Y).
Answer:
I'm sorry. I cannot explicitly give you an answer. The picture of the polygon is not provided. You may have forgotten to upload it, nevertheless, I''ll try my best to be of help to you.
Step-by-step explanation:
There are many different polygons. But the general formula to finding the perimeter of a polygon is:
P = n * l
n = number of sides
l= value shared and assigned to each side
The general formula to finding the area of a regular polygon is:
A = (n*l*apothem )/2
n = number of sides
l = length of one side
apothem = the value of the segment connecting the center of the polygon to a midpoint of one of the sides.
Hope this helps a little! You can always submit the question again with the picture and I'll be more than happy to help you. <3
The shape with 9 sides is a Nonagon the prefix non means 9 and the word agon means shape so the word nonagon means 9 sides <span />
