For a shape to be defined as a quadrilateral it has to have 4 sides.
For a shape to be defined as a triangle it has to have 3 sides, with the angles adding up to 180°
For a shape to be defined as a square it has to have 4 sides and angles. The angles must add up to 360° with equal side and angle length.
I dont know if i did this right but here
x1 = 9.5 y1 = 0
Answer:
Yes, they are parallel
Step-by-step explanation:
You can rewrite the second equation in slope intercept form to get your answer.
x-2y-8=0
-2y=-x+8
y=1/2x-4
Since the slope of this line is the same as that of the first, they are parallel. Hope this helps!
Answer:
The hypotenuse would be 37.58.
Step-by-step explanation:
c=a2+b2=162+342≈37.57659
B. (2,5)
For this problem, simply plug in the X values and calculate the Y value and verify that the Y value matches the value given.
A. (4,1); X = 4: 3x - 1 = 3*4 - 1 = 12 - 1 = 11. 11 does not match 1.
B. (2,5); X = 2: 3x - 1 = 3*2 - 1 = 6 - 1 = 5. 5 matches 5.
C. (4,3); X = 4: 3x - 1 = 3*4 - 1 = 12 - 1 = 11 does not match 3
D. (0,-3); X = 0: 3x - 1 = 3*0 - 1 = 0 - 1 = -1 does not match -3
And of the above, only option "B. (2,5)" matches.
