Three of those statements are true.
The only one that is NOT correct is:
<span>Any quadrilateral with one right angle is a rectangle.

50 because 50/100=2/4 and 2/4 is blue on the circle
Hello,
You don't know (a-b)(a+b)=a²-b²?
(-3)²=9
(5i)²=-25
Answer 9 +25=34
B) If the line is parallel, that means the slope is the same.
The slope for the original line is

=

.
The second form of coral line would be y = -1/4x + (any number). You could use
y = -1/4x + 3.c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So
yes, the third coral structure is perpendicular to the first coral.
