Answer:
9
Step-by-step explanation:
Once you plot this out, you can see that it is a parallelegram with a base of 3 and a height of three. The base is (-3,-2) to (0,-2) and the height extends to a y value of 1. You can also use triangles for this problem, but I would not suggest to do so because you can solve it a lot quicker this way.
Answer:
55% decrease
Step-by-step explanation:
To find the percent decrease
Take the original price and subtract the new price
140-63 =77
Divide by the original price
77/140
.55
Multiply by 100 to get the percent
.55*100 = 55%
55% decrease since the price got lower
Answer:
$255
Step-by-step explanation:
As, the area of the pool bottom = length x breath
= 20 x 15 = 300 square foot
So for painting
Per square foot = $0.85
So for 300 square foot = $0.85 x 300
= $255
The correct answer is it is a figure with at least 3 straight sides. When you think of a square or a triangle they both have at least 3 sides that are straight. A circle doesn't have any straight sides so it is not a polygon.
You can prove that the other answer is wrong because of two things:
The definition of a polygon is a plane figure with at least three straight sides.
Also, when you think of most shapes what do they all have in common? The have at least three straight sides
