Answer:

Step-by-step explanation:
-x/56x = 2
-1/56 = 2
x = -1/56
The correct answer is:
C. The polygon with 8 sides and a concave shape (attached)

2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40
Answer:
B. y= (2x/3)+4
Step-by-step explanation:
i picked a point and plugged the x and y into the equation to see if it would work
(example:
)
then i did the same thing with a different point on the graph to make sure it was correct :)
To calculate hypothenuse you use the formula a^2+b^2=c^2 where c is the length of the hypothenuse.
1. 5^2+7^2=c^2
2.25+49=74
3. Now you will square root the 74
4. The hypothenuse is equal to 8.6
