Answer:
No, she is not correct
Step-by-step explanation:
Given: Alana claims that not all 4-sided polygons with 2 pairs of equal sides are parallelograms
To check: whether she is correct or not.
Solution:
Any two-dimensional figure formed using straight lines is known as a polygon. Triangles, quadrilaterals are examples of polygons.
A parallelogram is a quadrilateral in which opposite sides are parallel.
Kite is a polygon made up of four sides with two pairs of equal sides that are adjacent to each other but it is not a parallelogram as its opposite sides are not parallel.
So, she is not correct.
So you question is most likely about a triangle DEF with the 3 angles being named D, E, F. The triangle would look something like the image attached below.
If that is what is being asked then i need more info to answer but
By Definition it would be 180 degrees.
Answer:i√6/6 , -i√6/6
Step-by-step explanation:
6x^2+5-4=0
6x^2=-5+4
x=√-1/6
x=±i√1/60=±i√1/√6*(√6/√6)=±i√6/6
Answer:
1: (3 ,- 4)
2:up (a > o)
3: -4
4: 2 units to the right
5: 4 units down
6: y = (x-2)^2-4
7:
8:
9: (5,9)
10: x=5
11: (4,7) and (6,7)
12:
Step-by-step explanation:
I'm not sure if you wanted it explained or answered , so i just answered most of them. Sorry if you wanted it explained.
Answer:
112+24x
Step-by-step explanation:
2(16+(10*4)+(x*12))
solve the inner bracket
2(16+40+12x)
solve this bracket
2(56+12x)
solve this now
112+24x
